After reading through the PFRPG( haven't played it yet)...Just wanted to throw in my 2 cents worth:
1.) Love the new system...not a huge fan of assigning all those points.
2.) The Fly skill seems useful...but sure sounds kinda weird for a skill...think it'll work though...
3.) Would suggest you make Tumble an opposed roll...vs attack roll of defender...a la...MCook's Experimental Might.
4.) I think Perception is a little too detailed...but again no worries there as I can use as much or as little of it as I like.
Overall, excellent work !
