IS 127 or IS137

[walter 1212]

Hello!

Two weeks ago my IS 131 was damaged. So it´s time to buy a new one. I want to know what are the differnecies between IS 127 and IS 137. My bodyweight ist 95 kg. With the IS 131 I used Severne Reflex I 9,6 and 8,6, once also 7,8. My next smaller board ist the IS 111 (2010). I use the IS usually on the lake.Twice a year I take part in competition. In the future maybe more often.

What about the fins, upwind-characteristics, planing.

Thank you for answering.
