Hey..I'm a Hurricane sailor. I changed the gear from the standard to the full SX last year. Great improvement, was it only for the handling. It is also a nice cat..one that has a nice design with beatifull lines. No big problems to keep pretty up with several cats such as the (older) inter 20 and F18's. But you need some practice, focus and good winds >4 bft. It is a tricky cat with trim..and you should sail it with a smile. You will not win the catbattle with it..and it is not meant for that.
Fot that battle you need a 30.000 euro brand new cat with banana features..these cats are fully optimised to have the best handicap-weight-sailplan balance, and do sail faster, but not necessarely nicer. For nice and fast sailing you need the Hurricane;)
