I have venom front castors, rear carriers and front bulkhead. First off rpm doesn't really count there are places where you want aluminum and places you dont so rpm for everything else. As far as quality they are not quite as good as strc and i have yet to try anza but they look good. They are however still good enough.
To answer your first post it ranks like this FLM/STRC-traxxas aluminum-Anza/Dynamite-atomik/venom/rpm-integy/stock-proline.
They are ranked this way for a reason I put anza where i would expect it to be although i dont have one of there parts. Rpm once again depends on the part. Proline i think is garbage that is too brittle to do anything with and will break very soon aka not reliable.
These are the parts that you want aluminum. Castors,rear carriers, front bulkhead,transmission, shock towers, and shocks
Thanks for great input this will really help as I select my hop-up parts. What do you think about the pro line power-stoke shocks?
