Elevator Turbulator tape question

I find this a very interesting subject (LS stab stalls) I have a lot of time
in the LS-6 and found no stab stall problems at all. The LS-7 was the same
until I put zig-zag on, then got an abrupt nasty stall. I only have about 50
hours in the LS-8, but I could feel and hear stab separation a good 5 knots
above wing stall when flying with 9 lb wg loading. My CG on all 3 was about 85%
of allowable range.

All three use a thin stab section and none come with zig-zag on the stab. If
I'm getting separation (nervous stick) a good 5 knots above wing stall, doesn't
that mean I'm getting close to stalling the stab? If I put zig-zag on the stab
and delay the stall, won't I be masking the tell-tail sings of stab stall?
