I'd like to check on the stiffness of the CA5 relative to similar priced skates such as the T6, RX25, and others. I'm really hoping to get a pair of skates that provides good value for money in terms of durability. I'm not too fussed about wheels as I'll be switching them over to outdoor wheels anyway. As such my main concern is with regards to stiffness/durability. The T6, I do know, has good stiffness for its price, but is slightly heavy.
