Komperdell 3-section twist and lock but no anti-lock. I am regripping the handles (plastic and/or cork make my hands sweat too much in summer), and I like an angled handle.
I never use the straps for downhill as I have a tendancy to keep my palm on top of the grip (the "ball" grip top is a nice feature for downhill, but not required especially since they usually only come as a single pole).
If you check out Beans, REI, or EMS, you will find their "brand" is actually made by either Leki or Komperdell, so don't rule them out either.
Good luck
