I am 160 lbs and want too choose between 2 boards for strapless kitesurfing.
HF 5'6 or the KP1.
Riding in Holland with all types of conditions but mostly not glassy waves.
Now ride a 5'11 strapples.
Which board must I choose?
That's a tough question. If you want more vertical pocket surfing then the KP1 would be great. The HF506 will also work well with more of an emphasis on light wind perfomance as it will want to get up and plane more and have a bit more float to it. Make your life better and get both! :)
Hope this helps,
