alright guys heres the ticket on durability of cvd bones from my own personal testing in the front with a oneway
softest:
composite
hpi alum
tc3 shiny
tc4 alum
:hardest
as ramon has previously stated even shiny tc3 bones will bend. this is because the bone necks down to a small diameter right by the ball at the end. it will bend at this spot.
the tc4 alum bone is ginormous compared to all the other avail bones. except the composites, its roughly the same size as the composites just alum. it is by FAR the most durable. running anything else is asking for bendage.
at least in the front. in the rear composites work fine.
i have no experience with the ti cvd's because of the fact that you cant use reg steel axles with them as mentioned above
tc4 blue alum dogbones retail for 21.99 per 2pack (the most expensive of everything i listed above
