which fins would you recommend for the Isonic 144WC with a neil pryde slalom mkIII 9;5 and a north stype 8,4?

My weight is 100kg and I put a lot of pressure on backfoot.

My options are select and deboichet. Select is the easiest to get.

If your just going fast with your mates or weekend club racing, dont be put off getting the cheape Select or Drake fins. While the Deb's are really nice fins, its difficult to justify the price premium for a few percent increase in peformance.

I'm 105kg and like lots of back foot pressure on this board. I'm using for 9m & 10m a Select RS7 51cm. Its a good compromise for power/speed. Iv'e had about 33k peak with both 9m and 10m, so its definetly good for mid thirty knots on the right day:) I know that the new Select S10 is working good on the iSonic's.

Like the Selects, the Drake R13 is a decent low cost fin, but the Select is defenitly a much nicer fin. Not tried the Deb R13 in a 51cm size on my iS144, but I'm sure that will feel much nicer than Select and Drake, but only slight improvements:)

HI Mark,

will jump into that topic since I also recently got my Isonic 144 and would like to know if you could comment about the upwind performance with a 9 or 10m sail and Select 51cm?

I have a isonic wc 144 / NP EVO II 9.5 and use a C3 Sting 52 cm for matchracing, 50 cm for down wind slalom. Ultimate top fins for use in competition (my weight 96 kg).

Best regards,

Hi Alex
9m & 10m with the RS7 51cm is good, I'd go as far as to say its nearly formula angles in 15 knot winds, lighter winds and it is OK. I also use a RS Ghost 57cm for supe light days (8k to 10k), bigger than recommended but helps to keep speed and angles up.

As Pieter says, good things are being said about the new C3 Sting, more lift and power than the older Venoms. Good prices as well:)
