my 2.0 had
every single ball'n part for the good and the bad... it was mostly for good, but weight came into play "sometimes."
for my 3.0 i want to keep the weight way down... that leaves with titanium to replace steel and CF to replace overly thick plastic... which means i might be out of luck lol. I havent gone to the extreme of buying a spare chassis and hitting it with dimple dies yet
