What attributes are you looking for? I generally want my boots to be as light and flexible as possible so your Mammut's sounds great.
I don't own a B1 boot. Never seen the need for them. Summer I just wear very flexible footwear, and use my Scarpa Manta B2 boots when I need the extra warmth and crampon use.
I am missing decent scrambling footwear, is this your use case? B2's are too cumbersome, and flexible footwear tires my feet out. Is this your use case?
> I've had some Mammut Trovat Guide II High GTX boots for the past few years but have never found them very comfortable and quite difficult to climb in.
What was uncomfortable and what made them difficult to climb in? If you prefer a stiffer heavier boot just go with B2.
