1) The screwdriver test is good.  Try it with a small sharp object too, like a pencil tip.  The results may be the same??

2) I did NOT use the Kevlar in the standing area.  There was enough carbon not to worry, meaning 3 layers of Tri-Axial 30/60/90 degree 5.8 oz carbon.  My mistake was making the last board with a gloss coat on the standing area.  Best to let it breath, even if you perforate the lamination.

3) Be wary of roughing up the surface too much with XPS.  I use 220 grit sandpaper only.  Just take the shine off the XPS.  People have been using Bee-Rollers and heavy sandpaper to increase adhesion to the XPS.  I have found that under 'normal' conditions there is no reason for the laminate to separate from the XPS.  The pressure from water, and board bags is literally NOTHING.  It's knees, and heels and peoples fingers (Thumbs), and dings around the garage that you worry about.

The squeeze test is also a red herring.  People will grab my boards and say "Oh that is soft . . ."  Keep your thumbs off my board!!!!!!   Meanwhile there board has a hard candy coating and weighs 50% more than my board.

I will try the test with a sharper point but i think the results might get a bit random.
With the Innegra the same blow will rebound or not and i think the difference is where in the mesh the point of the screwdriver hits.
If it hits thread it rebounds.
If it hits perfectly centered on the space between threads it penetrates easier.
I think a sharp point might exaggerate this variation.
We'll see.
Anyway, other than the pesky car door corner most hits are from (thankfully) non pointy stuff

I guess i will get used to a softie deck.
I have packed some extra volume in the nose (bit of bubble nose,4cm higher than deck)) to move the CB to midpoint.
This has the advantage of reducing nose lenght and increasing its thickness so i hope the stiffness will be good with not much flex or buckling.

I have sanded with 80 grit on previous boards but will try 220.It should take less resin.

Rocker is cut on nose and tail, next job the outline and boxes :)
