I really find it hard to beleive that heat from the pipe is doing damage to the spare belt.
Think about it, the Velcro strap is in about the closest proximity to the belt... I have never had the velcro even come close to melting... Spare belt is new, not broken in... No marks, no signs of excessive heat, etc.
I really feel for the guys having issues... I have an 08, and I toasted my first belt, 060 (without venting) it was heavy deep snow and it was warm weather... I chalked that one up to abuse on my part.
Since then I switched to the 046 with lots of venting... Got 700 miles or more on the next belt... It started to pull a cord one of the first rides this season but it was worn big time, width was waaay narrower than stock, that belt never came apart... Looked like even wear to me.
I think the flowrite(s) in front of the primary helps a lot... I also drilled holes in the back edge of the side cover... they are open and no snow gets in.
I have noticed that you can do all the venting you want, but there is very few places for the air to exit.
I set deflection a little on the loose side and have not had any issues.
Never have checked alignment... If it aint broke, don't fix it right?
