spike, i hear so much positive info about the xp series i'm curious, will there be a night/day differance between the 51 and the the 357xp?
O'Yeah , night and day difference in my oppinion The RPM of the 357XP is 14000 and the 51 is 12500 , there is a lot of difference right there.
The 51 has 3.1 hp and the 357XP has 4.4
If ya ever had a chance to shoot up to lower Nebraska I'd let you take some XP saws out for a whirl. I couldnt believe the difference until i ran the XP saws.
Our ole buddy ELK just picked up a 357XP and posted a thread on it if you want to look it up.
