I have and am VERY happy with the Powerhouse alu 1-piece! I know CF should be as strong but I still feel better with alu going over gravel etc. TQ, strenght and weight wise they are compairable. I actually think the alu ones are a bit lighter than the CF one...!?
To make your own you have to know a great welderer. Plus balancing can get VERY pricey!
The CF is probably a little more prone to getting chipped which will have adverse affects on strength. Not that I go over gravel very often.
