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.

moog-
I also found with BB7s that my big feet kept moving the adjustment knob until my brake eventually locked up ( the brake mount was inside the rear triangle on my Ogre )
Was much happier with Spykes after that

That’s fair.
I don’t mind bb7s. I have the same irks with them that you do, mainly the misalignment of the pads which makes getting them to run rub free and with decent lever feel difficult.
The concave/convex washers are as much a curse as they are a blessing too I feel.
I think I’d be more likely to shell out for Klampers than some super fancy Hopes or something. I expect though that I’d get the same performance out of a Shimano mechanical caliper.
The Growtacs are yeah about the cost of used Klampers, more readily available though as I only have IS/post mount bikes not flat mount which seems to be what a lot of the Klampers are. Could always run an adapter.
There’s hooky Growtacs on Aliexpress which I’m tempted by, would feel a bit shit buying fake Paul stuff but Growtac seems more like a faceless corporation? Maybe they’re not.

Would you be tempted by Growtacs?
