Thanks for the input.
I got my hands on a compression tester and am going to test it this weekend. It's been so long I can't remember what PSI numbers I should be looking for. Anyone have that info handy?
As far as plans go, I used to have Toomey T5's on my last one and I liked those. I may get another set or get the TR6 but I have not really researched the difference.
We do mainly trail riding and there is a big gravel pit in Mississippi that we like to go to also. We are pretty much at sea level and mostly ride in 90 degree weather.
I'm not trying to go fast in a straight line, I just goof around in the woods, etc. and love the thrill of the banshee, that's why i got rid of the 450!
Thanks!
