On road sections I average 35-40 but honestly I just prefer the looks of a disc and a little more strength when bashing stuff off road. The bike IS setup for racing

If so, it'd help greatly to know that those issues are. Otherwise you might be handicapping your choices of otherwise better cranks. In the belief that you will somehow cause them to fail.
My issue is with eating a BBs a couple times a season and have also slightly bent a chainring trying to clear a log. Currently SRAM DUB and want to try a crank with a 24mm axle for the larger bearings and hopefully get more life out of them- my FTP is only 280 on a good day but ride in harsh conditions. I want an aero type because I like how it looks.

Honestly I think the answer is rebuilding the BB at regular intervals instead of waiting before it gets crunchy - and up my bunny hopping skills so I don't bend stuff LOL. FWIW the bike is a Grevil with SRAM Force and GX rear mech.
