i cn only speak for the ar6 because i dont own the t-hall
park(ill divide into kickers and rails)
kickers- 9.5 -because not fully symmetrical makes switch landings a bit harder
rails- 8 - again not symmetrical and i mounted mine at -1.5 so teh swing weight factor
groomers 9.5- excellent for a park ski
general playfullness 7.5 -because they are on the stiffer side, but are very stable and plow well through chopped up stuff.
overall id give it a 8.5
hope i could help :D
