To be honest I don't even know why I bother, obviously zildjian understands the clear advantages and after seeing all your other posts I'm not too sure you can tell your *** from a hole in the ground.
Does anyone have bigger butterflies for these? Couldn't I take this to my machinist and he could probably bore out the TB and put some bigger butter fly valves in. Sure might cost me $100 or so but if it could help me pick up some I would be okay with that. Is this something people normally do?
