You could try the 683 it will bolt straight on.
I t will give you maybe 20% more speed than the 633.
The 590 is great though and is a bigger wing for your weight. The 590 will also match the 90 mast well
The 590 top end will be a fair bit higher than the 633 and will be really easy to control at high speed
If you want to tour around at speed then you will enjoy the 590. It carves as well, higher winds will be more fun on the 590
Hi Ben, tried 683 and felt it was marginally faster (but much less smooth) than 633, not enough to want it (I would judge it to be 10-15% faster).
I posted this question in another forum. The answer vary greatly - some say I would get extra 5-6 knots of speed, other say it would go 50% faster. What is your assessment? Have you happen to have GPS speed of both to compare the top speed?
