We've already started the process.
I just talked to Todd over at PRO and he's going to be using .125 wall dom tubing for the LCA's. Also, the problem with the Stock LCA's is they're pretty damn flimsy which causes problems. He also told me they'll probably weigh about 5-7lbs each.
Anyway, we'll have a prototype done up here soon enough, so keep the suggestions coming.
