What barrel/freak sizes do you commonly use?

[powpowpaintball]

.684, .687, or .689 freak insert, with the .687 staying in unless I'm breaking paint.

I pretty much only use .680 back or maybe .685.

[Beaver]

.675 and .680

Paint is small, and I need an undersized fit.

.684 sees the most use these days with my open bolt guns. .680 UL back or .679 Freak back with my cockers.
