Dont forget that there are no less than 4 aftermarket companies making D60 centers. Though I'm not convinced that doing this hybrid would make the strongest axle out there, but possibly the strongest cheap axle. I know the Sunray 1550 setup has been breaking fairly regularly in competition possibly because of the extreme turn angles they are trying for, and I've never seen the 60 CV actually on a vehicle. If you want a bulletproof 60 the CTMs have been proving pretty tough for the majority of teams. Problem is if you want CTM one piece axles and joints its gonna cost $$$. I know for a set of 8 axles (4inner 4outer) The materials alone were over $3k I think if you could find a way to put the rockwell knuckles on a 60 and use those shafts it'd be a lot cheaper and at least close in strength. Then if you wanted to get silly and upgrade to a 40 spline diff and get some of those HUGE aftermarket rockwell shafts you could really put a beating on em.
