Well I have the Tsunami Ultrawide, which as you may or may not know came with the extra long aluminum a-arms, plus I've upgraded to the aluminum c-hubs and hex nuts. I've had it for 5 or 6 months, I've beaten the everliving crap out of it, flipped it literally countless times, ran it into just about everything you can possible imagine, and I've yet to bend a single aluminum part. Now they've gotten scratched up, and even had chunks of aluminum knocked out of some of the a-arms, but nothing is bent, and still holding up as strong as the day I got it.
