Board advice

[JamesH]

Relatively new to the sport, I am aiming to do the RYA intermediate course this summer and am looking to buy some kit. I don't want absolute beginner kit with a dagger board as friends have all told me I will grow out of it too quickly, so my current thinking is that I will probably buy a Go 151 (seems to be a good compromise) although somewhat confused by the difference between the Go's, the Carve's and the Futura's. Obviously the 151 has the centre fin but there is a Go, Carve and Futura 141, what's the difference between the boards and their relative pros and cons? The Go's and the Carve's seem particularly close in design and I am wondering whether a Carve 151 (or even possibly a 141) may be a better bet than the Go?

Thanks
