I suggest beg borrow or "steal" a dedicated foil board, regardless of size I suspect you'll get a good baseline for what size will work for you.

I've noticed that once under 8ft volume is the dimension most likely to influence my foiling, as in less volume gives me trouble,  Also less weight always helps me.
