Edit: just read your title again, "confident or experienced foilers"..... I'm neither.

I'll get back to you.
I decided to jump in the deep end and am learning on a KFA Mako.
I have only got out on reasonable choppy ocean a couple of times so far and not a lot of success yet but felt a bit better and went a bit further the last time.
I am still waiting for some days with good conditions when I have the time to spend a couple of hours.
I am still fairly heavily addicted to downwind SUPing so am just taking it easy and getting out on the foil occasionally, most of the time it is to windy lately so I have ended up kiting with my surfboard or SUPing.
