Might look at the Schnees timberlines. Never had a pair but seem to be exactly what you are describing. A bit taller with more flex in the sole. Good sale going on right now too.

I think your theory has legs....Ty Stubblefield was one of the founding members of BRO. He went to work for BHA. He became disenfranchised with BHA leadership. He is no longer with BHA and speaks openly about why he left.
Darn tough
Sent in 4 pairs and they warrantied all of them. Great communication and service.
Wrangler Jeans
Sent 2 pair in as they have a one year warranty. Back pockets started ripping off and the crotch ripped out on one. Only wore a them few times. No communication whatsoever. 5 weeks...
