The 08 Flare 88 is in fact a very nice high wind riding boards in general. Fast and stable. And it has a rather narrow tail, so the single straps is not a problem. It's a really nice carver too, especially in fast drawn out jibes - the harder and faster you push it the better. It will still be rather big for seriously powered up 4.0 riding for you (for that you would need to go for something considerably smaller, like a Acid 74). But as long as you rig a bit small and stay out of the overpower range, the Flare 88 will work nice with 4.0 too.
So overall, the Flare 88 is more all round than you might think, and if you have freestyle ambitions it seems like a very good choice.
