Others can help with stick or shorty pack, just getting mine out to the track for the 1st time today so I'm just figuring out my tune for it.
Shorty I would think is the way to go, gives you more weight placement options. I'm running stick for now because that's what I have already.
SMC is the best deal on packs IMO. Factory spec is good, race spec is worth the extra couple bucks.
