We all remember when there wasn't trials specific stuff, and I for one remember almost dying on a number of occasions. With regards to you not being gentle on stuff that maybe so, but were you putting much pressure through them? I'm gonna guess by your current Rocket you arn't exactly a TGS rider who does power move after power move.
Back when I had a Hope XC I had to send it back to Hope for a repair and borrowed my brothers Deore on D512 rear wheel. I killed the freehub within 2 hours of putting it on my bike. This is going back 10 years or so, so I wasn't exactly going massive.
Since then I've killed 3 trials specific hubs and a couple that wern't (Kings). If you ride trials to a modern standard, yes stuff DOES have to be strong or you WILL end up with no teeth.
