Wow I didn't even think of a revo I bet that thing would fly (or rip itself apart) with the sts. I like the looks of the revo I guess i'll start looking at those as well. I decided against the mammoth and now i'm stuck between a used lst 2, keeping the savage and upgrading parts, and now I guess a BB Revo. Oh and im set on the sts 30 now; I just snatched a dadders stage 2 sts 30 for $127 on the great ebay!
