After some 10 foil sessions this season I am considering to buy a dedicated foil sail for 'recreational foiling' . I have a Goya Bolt 127 L, paired with Neilpryde Glide Wind (small) foil. My weight is 79 kg, and I have been using a Goya Nexus 6.7 freeride sail, and a North Sails 8.2 e-Type. Both sails are feeling overpowered in stronger winds (above 15kts). Also I am struggling to maintain constant height, constantly going up or down.
I saw the review of the Sailworks Flyer and they discussed the increased stability the Flyer concept brings with the 2 cams. I very much feel that this is what I need, on top of easier pumping-to-get-going ability.

Now looking at the market in Europe where I am based:
1) the Flyer is not available here (needs to be imported from US... costing in the end around 750 EUR) and
2) DuoTone is offering the F-type 2019 at around 550-650 EUR.

Comparing the two concepts (Flyer 6.0 vs. F-type 5.8) side-by-side I see lots of similarities (see below for visual comparison):
- both have 4 battens
- 2 soft cams
- reduced luff curve
- lowered foot area (below clew)
- dacron luff panel
- both said to be light
- and both recreational foil oriented

I am tempted to go for the Flyer and incur all import duties that brings with it (the guys at Sailworks give a nice discount), yet I wonder if the DuoTone will do exactly the same for less. In the end DuoTone is not a lousy brand. A key consideration is that (for budget considerations) I will need to pair the sail with a Goya 430 70% carbon mast, icms 21, and bend curve bottom = 64% and top = 78%

I also am considering a Hydra Sport 2020 5.7 and Goya Bounce 5.7. The Hydra is most expensive of all, and my mast is less suitable. And the Bounce is suiting the mast well, but has less foil dedicated properties.

So, questions to my fellow foilers:
What do you think? Which to take? Has anyone sailed with the above sails, I'd be interested in a comparison!

Thanks a lot!
