Generally speaking Sharky, I'll agree with you. But there are some times when a snap roll can come in handy.
If you've got altitude it may provide you with a means to extend out of the fight. I was flying a hawg and tangled with a pony at about 15k. We stayed about 15k but I had pulled a couple turns a little too far and burned a lot of E. The pony was getting low, but still had a little more than I did.
Anywho, this pony is getting ready to chew me up, saddling up good and closing to about 300yds. I kicked the rudder hard, pulled the stick to me gut and snapped right outta the line of fire. Let the bird roll over twice and pointed me nose at the ground and flew away.
