I'm a lot heavier than you! 105 kg.
I think that if I pinched less I'd be able to trap more.
Also err on the side of trapping when you shouldn't. Ive seen the euros trap much earlier and the thought is that keeping the boat flat and the mast perpendicular is more of a performance advantage that desperately trying to get a hull flying. I've been taking that approach and it hasn't hurt me yet...and I usually sail heavy.
