Thanks all responded. The idea steveC was pleasant:-) but while the final decision has not accepted.
In a weekend I will go I will look 161.
As to my experience. The first year used the big board with רגונעמל (The big central fin), the second year JP FREERIDE 159. On it I use a trapeze and has risen in loops (not so confidently). Would be more wind, progress would be big:-). As already speak, this board not for our conditions.
Now I want continuation:-)
Opinion local windsurfers were divided approximately fifty-fifty :-)
