What is the best shapestyle board to make and learn with

[H C]

Hello I am new to Kitesurfing and would like to build my own board.
I weigh 100 KG and am wondering what would be the better shapestyle board to make and learn on I could have a go and try to make a cheap directional but I think that I would prefer a big twintip.

Please bear in mind I have never been on a kiteboard I feel that I can body drag up wind and relaunche proficiently and spent a few minutes trying to get on a directional I think now that I need to spend time practising by myself and recon that the cost of a beginner board is nuts.

I am 6'4" and am wondering what length and with would be best then there is the pointed or double pointed or even square ends fins etc.

Thanks in advance

my (80 kg) first board was 5' 10" x 1' 10" twin tip. Easy to start learning but soon I found out that it was too long (did not handle gusts and it was not fun to ride in strong winds). After 3-5 times I started to do smaller 5' x 1' 6" twintip. Volume (big fat boards) is not usefull in this sport.

I recommed 5'2" x 1'6". Big fins and take the outline from Airush square ONE. That should be good for learning and also good for light wind days in the future.
