Which deb?

[zalcort]

Hi!
I have a question:
I am 74 kg and use 2010 iSonics 111 wood –carbon
I use 6.7 - 7.2 and more frequently the 7.8 Neil Pryde RS Racing sails
Spot condition: flat water –small chop (slalom condition)
Which deboichet fins would you recommend?
I don’t understand the different from Sl2 and SL4 models
Many thanks

Hi Zalcort

The SL2 is more for reaching performances and will be perfect for Slalom 8 course and the SL4 is more for Slalom Down Wind Course. To compare this 2 fins you need generally to take the Sl4 2cm longer than the Sl2 for Slalom down wind.
So both profile will be perfect for your board, just depend what you will do with it.

Hope this help

All the best

Thanks for your quick answer
Ok now i get it
So the follow combination it could be correct for my board and my weight?

6.7 - 34 sl2 /36 sl4
7.2 - 36 sl2 / 38 sl4
7.8 - 38 sl2 / 40 sl4

I think the sl2 could be better for me because I don’t make only down wind slalom, I need to sail up wind also.
Any suggest?
Really Thanks for your help and good job

Hi Zalcort,

For reaching and up wind performances better to have the SL2 in same size as SL4 for down wind.

All the best
