Riffe guns blow in my opinion. I've had a few (except the euro's) and hated them. Muzzle jump and recoil were some of the major issues. The island was the only gun I have ever shot in my life where I could miss a point blank shot.
I believe jbl is now making a product up to par with riffe and they cost so much less.
A great wsb gun is the new jbl elite mid handle if your on a budget. Or you canshoot em with euro guns. The speardiver euro in a 120 or 130 would be great.
Edit: Don I have shot a bunch of whites with my 90 and a flopper. Never lost a white with flopper shaft either.
