M_V-
I don't think so - price wise they are similar to second hand Klampers and I don't know what advantage they would offer.
Thinks I don't like about BB7s:
- they don't always push the pads totally parallel
- the plastic adjusters eventually break / get lost / melt at high temperatures
- when the pads wear the outer piston has a habit of over extending
- after extended use the grease dry up in the caliper and the actuation arm jams
- if you aren't careful with the cable pinch bolt it can fowl the caliper body and cause the arm to stick/jam
I think the Klampers solve all these issues but equally I can rebuild a BB7 with my eyes closed and am pretty sure I now know every nuance and quirk they have by now. If I do get Klampers it will be a vanity purchase. The serviceability is the main attraction but I could get x5+ sets of BB7 for that price.

On the Straggler? I had the bb7s and avid levers already and I'm on a zer0 (or as little as possible) additional spend policy on it. I also have a lifetimes supply of spare pads after I panic bought loads when we re-upped in Bolivia.
Good point on the skewer, I think I might have a set of halo skewers with hex heads in a toolbox somewhere.
The Rambler is also going to be mechanical - for now Paul Love levers with bb7 calipers, although @MrBaklava is on a campaign to convince me to treat myself to Klampers (and he might win).
Maybe with the bigger tyres I'll want more power/control than the bb7s can offer but I've not felt the need for more on the Surly.
