174 3" or 2.5" on boosted pro

[Dirt2oil]

I plan on doing a 174 on my boosted pro. Now I'm stuck between doing the 3" or the 2.5". Any input on this, pros n cons between the two track sizes? Would the 2.5 be better to keep my track speed up or go 3" for the traction? Any feedback is appreciated

3" all the way i've seen the difference first hand on a doo and a pro both stock and they climbed like bill goats! This swayed me to drop and roll with a 3" x 162" on a boosted dragon @12psi.
