I like that a duck bill brings the tank back slightly. I also feel like an on/off is just one more thing to leak. Most people say they save your threads but I play a considerable amount of paintball and have never damaged my reg bottle threads or have I had a problem removing a bottle. Let me hear what you think, on/off vs duck bill!

When On/Offs came available (eons ago) I completely got rid of "duckbill" ASAs. I like not having occasional o-ring damage when screwing off the bottles and the ability to degas the marker with the bottle still in the ASA. If I need to extend the length I either use a longer bottle or add an extension but really not an issue for me. I still use 45/45 bottles and 45/50 peanut bottles occasionally. I really do not "shoulder" the bottle it is not like it has any real recoil to compensate for.

I personally prefer an on/off. I have changed less tank orings because of it and it makes teching markers much easier. I do prefer a longer setup on my pump markers though. i went with some of the powerhouse tank reg extenders and really like them. prefer that to the long version of their regs.
I can say i have seen more than a handful of minis that had the original no on/off asa that had their tanks permanently affixed to their markers because galling from the aluminum bonnets.BeardedWorks.com (Your Inception Designs and Shocktech Dealer)

Duckbill is classic and simple, yes. But I like to not have to fight a tank with air off the ASA. Degass, unscrew with ease, swap the tank between markers easier. My favorite on/off is the CP direct mount, since it's so smooth and it extends back more than modern ASAs that are flush with the frame unless you have a rail or it's T slotted and you can adjust.Comment

I would rather have a duckbill than a non-purging on/off💀 PK x Ragnastock 💀Comment

I like on/offs. And yes, purging are better. Only on/off I never like are the Dye Airports. Always felt like that level would break.Comment

I don’t really care either way as long as it works. If I was building something I would definitely choose an on / off. But like my Emek still has the original ASA and I see no need to change that out for an On /Off.Comment

I've has some duckbills that are fine. They manage to degass the marker in a turn or two of the tank, issue is that's dependant on so many variables.
I have a ninja ball valve reg I use with an ACI duckbill I have on a RTP build works fine together. But I've pulled many non on off regs off almost instantly because they don't degas, and or they degas so late, you have to rotate the tank 4 to 5 times before the pressure is released. Those are junk imo.
I still dry fire the marker while rotating the tank to shock the threads off in an attempt to save them some.
All in all, I prefer an on off any day of the week. For so many reasons. An obscure one you may not have considered. On a lvl 10 mag that's exhibiting bolt stick. I've managed to stay in a game by degasing, holding the trigger down, and re gassing on the fly in a firefight. With out an on off I would have had to flip the marker remove my barrel, hope I got the ball out of the breach, and reset the bolt.Comment

As mentioned I hated shotgunning a tank oring every time I would remove the tank. I put an on/off on almost all of my guns. I have noticed that the threads in non/on/off asas can get very sharp when using a high output pressure tank. The only on/off that I really love are the Bob long direct mount ones. They are small and mount to frames flush without a rail. If I have to use a gun with no on/off then I use a tank extender with twist on/off. I can't remember who made the good ones at this point, but I think it was NDZ.Comment

It seems I'm alone
I should have made the point that I do understand their benefits but do not think the benefits are worth 50ish dollars.

It seems like the kinds of tanks I use determine how badly I need an on/off.
I've had some older Ninja regs and a DYE Throttle that always felt like they were getting chewed up as I used them on duckbill bottomlines. Conversely, my ancient Crossfire reg and newer GA regs with brass bonnet threads always feel nice and smooth, even without an on/off.Comment

Exactly this... I bought my first ASA (from Smart Parts) because my Nitro Duck cut o-rings every single time. I tried hard PTFE orings for a while, but even those were getting tore up. This mattered a lot when some guns would have issues that required degassing the gun to fix it and you're a half mile deep into a scenario field.

Back in the days of C02 having the on/off saved you a few tank o-rings.
I still prefer an on/off to a duckbill even w/HPA....it's just preference. Some like big tits, others a nice ass

It depends on the marker - a duckbill mounted to a UMB on a Sheridan or PPS marker is lovely and puts the tank juuuust right but other setups feel better with an on-off.
I even like small drop-forwards with duckbills - the combination can work well on something single-tube, like a Mag. It puts the body/barrel up into my line of sight and doesn't sacrifice overall length.Comment

I typically don't like duckbills with out a drop. A duckbill on a WGP STO drop with a 68ci tank is about perfect for me. I really like the kapp micro ASAs for my 45/45s though they are hard to find these days.
on/offs, I remember many people loosing pieces for them or having the threads from the knob unscrew from the pin depressor on the older designs.Comment
