Building/tuning a STBB

[Psycho91]

If I changed a valve or 2 out which would y'all recommend the balance valve from the vs line or the eko valve

It's the stock valve out of later Spyders. The valve pin is designed in such a way to allow more flow and blowback is provided via a small hole in the valve rather than the valve pin. My hope is to increase volume/flow so therefore I can use lighter springs/striker.

Which later spyders? I've taken apart pretty much everything there is outside of the balance valve and spyders have always had the cut out of the valve stem not a hole in the valve itself

There's a lot of stuff like JT and off brand that run the valve hole but I've never seen it on a spyder
