I really like most of Norths products, especially their Warps, masts and booms, but for £300 for the Shox, I'm not convinced its worth the extra .001% gain or hassle with breakages etc. I loved the concept of the XTR extensions, but spent loads of time sorting repairs. Also, we use loads of effort maintaining mast foot pressure for early planing, speed etc and I feel that the Shox could counter this. Could be wrong, but until im 100% certain that there are easy gains, I'll not be getting one, "for now"
P.S. Jimmy D has been training very hard this year, that could be why he has had a great start to this session. Would like to see him do well this year as he's a top guy.
