What’s you gut-feel on how ready for harvest this is?

You have at least a month to go in my opinion, those buds haven't even really started swelling up yet. I wouldn't start checking trichomes until the pistils start turning brown and curling up.

Weeks and weeks away m8. Do not chop and don’t bother sampling.

My gut says 4 weeks, but given this particular strain, it may only be 3 weeks.

3-4 weeks she's only pre-flowering.

Oh long time buddy, your buds are still forming, at least half the time you've been in I'd say :) Good luck !
