Why do you want such a big board anyway?
I was 115kg now 105kg,
and i ride a 132x41 board. It gives me plenty of lowend and works perfect in highend.
The brand of the board doesnt excist anymore but the evolved shape went to Fluid Kiteboarding.
Its now called the Fluid two/seven. From what i hear the board gotten even better then it used to be. But well testing is knowing.
been testing the 135x41 droid2 and Oxygen V2 135x47 and i really do like these boards aswell.
The droid would be my 99% of the time board. But the Oxygen gives me that extra lowend without loosing playfullness.
Wider tips will give you a straighter outline which is nice for upwind performance and will give you a little extra float to compensate weight.
I personally dont like really narrow tips either.
