Hi Nick, a lot of the questions above are often very personal depending on skill, fresh or salt water due to lift, swell/chop or smooth water and then also time on the water with a foil which makes everything a lot easier. anyway I try to answer a few q's:
- 1000 Flow you can use also in super light wind if you have foiling skills, but as your level described above, probably 15-20knots. The 1500 Flow from 8-15 knots, the 1250 a touch later. But again, a lot of this depends on your skill level and how much lift you like.
- No, use the 4 screws rather, put it right on the middle of the boxes and if too much lift, go backwards step by step. Forwards if you miss lift. You really have to stop and adjust every 10mins here, even if it's a pain, to experiment with finding your ideal position.
- If no shops have a 1000 Flow, then I can highly recommend the Free 1000 front wing, no need to change back wings - use the Flow 215. We'll be offering that as a replacement to the 1000 Flow soon officially.
- Outboard/inboard is really also personal - inboard and no back straps to learn, pretty much like fin riding - and then move outwards as your skill levels improve.
Overall sounds like you need to do some tuning/testing and above all just keep at it, foiling is not learnt super quickly, pretty much the same as windsurfing, but it does not take a lifetime to master at least..:-) good luck!
