Just an update to this. I ended up switching to a 60cm (24in) 360 and I'm actually playing much better. I can 4x spray very accurately now, recoil is slightly easier to control, and I don't have any of the problems I outlined above anymore. One thing that was affected was my accuracy with quick headshots with a bolt action sniper but I feel just a little practice I should be able to get back there. Maybe in a year or so I'll try 50cm/360.
