Savage 21 BL Conversion - From The Beginning...Advice Appreciated =)

Hey man, thanks for your help, much appreciated!

spewbags bout the piggybacks... i only bought em cause i've always loved the look of em, but guess i was dumb enough to not do the research -lol- Do you guys know if the Losi TiNi Shock Shafts will fit the Integy shocks?? Maybe i could get away with em then? =)

It looks like you've swayed me to lock it up in 2nd tho =) Speed is not a main concern - as long as i'm, as you put it, 'too quick for a track' - then that's exactly what i'm after =D

How many spider gears for my diffs should i be looking at? I've been thinking of going for 6, but does the count of these affect driving at all, or just add strength with the more gears in there you have? (eg - 4spider= strong - 6spider= strongER - 8spider= strongEST???) Is HPI the only company to make these spider gears?

Sorry for all the q's hey guys, but the savage is brand spankin for me -lol-
