Savage X specific questions

Next, i have already stripped 3 spurs on the truck. I am going steel. stock gearing is 15/47. if i eventually wanted to get a LRP .28, i would want to gear up right? HPI sells up to a 20t clutch bell, so should i get a 47t steel gear? Or higher? How much am i going to have to gear the engine up.

Next - wheelie bars. Integy sells one - http://www3.towerhobbies.com/cgi-bin...?&I=LXKWW9&P=7
it has aluminum arms, and two wheels. HPI also sells one for $2 more that is all plastic with 1 wheel.
Any reason i should stay away from Integy? if so, what would be better?

Last... shocks. How are the stock shocks? are the new flux shocks much better? should i save up for the LST conversion kit???

I will post any more questions in this thread. it will be a single thread for me to ask savage specific questions. ----Thanks, AD

EDIT: couple of nitro specific questions have been removed.
