Hi Tuny,
I think it will be fine.
Actually the worst model (pattern) I've ever had for this was a PL Partner.
On a set of spins, properly stalled, it would do 3/4's of a rotation after release. It needed a pile of opposite to get any sort of accuracy.
I may have had a slightly rearward (can't remember) cg but nothing excessive.That had a chunky tip section and a blunt LE.

Matt,
' In my latest design, Delta, I went to some extreme in reducing tip thickness percent. My chord was very small already at 7" (thickness of around 0.55") so my LE radius became very small. That small radius (1/16") I believe is causing unwanted inconsistency in snap and spin exits. It's just too small a radius and is not allowing as smooth a flow over the tips as I am accustomed to.'

That is almost exactly the size as mine are but obviously there are two each side on a bipe.
Hope I have not over done this.
I will dull the LE a little just in case but for the single snap on top in the new FAI 'P' I'm looking for an instant bite.
I think , assuming my weight calculations are correct, that the loading will be the key. This is the plan at least.
I also think that weight distribution is very much in play here. Again , assuming I get it right, the outboard weight will be extremely low and coupled with that close to zero flex I'm expecting it should be fine.
