Thoughts on 90X tranny and weight

[EJ Racing 07]

My son runs a Apex pro 90 but I've always liked four strokes. How is the tranny going to hold up to mods being its a reverse and is it heavier then an Apex? I'm a believer in the less parts the less there is to break theory and with the reverse there is diffenitly more parts. So whats your thoughts? Anyone have a 90x modded out yet and is it holding up?

My sons parts should be in towards the minnle of next week. Right now we are putting everything out so far on his quad, cdi, exhaust,& rear clutch. His first hare scramble is March 9 so I guess we'll see.
