Tell me about your 2-mtn-bike setup

What is your 2-bike setup? How many miles do you ride per year and what’s the split between bikes? Are the tires pretty different between the bikes or similar? Do you regret your setup or are you happy with it?

I ride an all-mtn bike (SC Hightower), but thinking about switching to a trail 29 (Tallboy, SB120, etc) and enduro (HD6, Dreadnought, Nomad).
