Inflatable wind sup

Already on my desires...
Will the smaller "Whooper shape" 10' be suitable for wave windsuping?
Is it good the centreboard version that I prefer for this purpouse?
One could replicate (wood?) the fastbox inserts... and so doing make a powerbox-fastbox?
You are testing the market answer before going on with windsurps or there is already a 8'10" on project for 2014?
Footstraps inserts in a inflatable in the future.. too much?
Maximum suggested lenght of a fin using a fastbox?
