Ok so I'm planning for the fall/winter indoor season and it looks like the track where I will be racing is going to have a stock 17.5 blinky class which they didn't have when I was there last season. I really think slowing things down a bit will be good for me so I'm going to race this rather than mod. So this begs the question: what motor and gearing should I be running?

I have a Viper VTS17.5 in my son's XXX-SCT that I could snag but I know that may not be the best choice of motor. So what's the hot 17.5? Reedy Sonic? Trinity D3(.5) (that is legal again right?)? Other? Then how should I gear it? I have the AVID 'stock' Triad kit sitting in my pit box which comes with a 72 and a 76 spur. RC GearHead suggests 72/29, 76/30...is that a good starting point?

Track is smoooooth high grip clay with wood jumps...would small bore V2 shocks with BB springs be a better choice than BBs (I was reading some prefer that setup)?
