So, I've just ordered a custom 853 Curtis hardtail frame (can't wait)

I'll be re-using the following from my very old Santa-Cruz
DT Swiss 120 Forks
Easton carbon bars and stem
26" Hope/Stans wheels
Hope brakes

But...

Do I go for a dropper, and if so which one

Do I stick with the (very old) triple XTR Groupset I've already got, or go single front, and if so which cranks/mech


Too much choice, and two months to think about it
Condor Super Acciaio, Record, Deda, Pacentis.
Curtis 853 Handbuilt MTB, XTR, DT Swiss and lots of Hope.
Genesis Datum Gravel Bike, Pacentis (again).
Genesis Equilibrium Disc, 105 & H-Plus-Son.

Mostly Steel.
