Agree it's a tribute to both lines; I also believe splitting hairs (like splitting atoms) is sometimes necessary ... and can likewise sometimes be explosive
I actually believe more hair-splitting is necessary
I think most Bolio/Tombstone dogs are thin-boned curs (Bolio more so;
By constrast the right Bolio/Tombstone dogs are some of the gamest/smartest best dogs on earth IMO.
In other words, you're not just selecting any B/T dogs, you're selecting BUCK and LADY IN RED DOGS, aren't you
Same thing with "RBJ" dogs; some of those are long-haired, fat-tailed curs as well ... but the right RBJ dogs are what you just described. (Although I would say Bolio dogs are smarter and more prone to having a "Plan b and c" than RBJ dogs ...)
I think certain segments of these families are great ... while others are not so great.
I think the BUCK/Hollingsworth dogs are the best of their line (Boyles too) ... and Yellow-type dogs are the best of those dog. I realize there are some small, very private pockets of similar dogs that are also good, so I am speaking very broadly.
Quite frankly, I don't think your dogs have much Tombstone blood in there at all, and might more properly be called "Buck/Yellow" dogs ...
If I personally had to choose between pure Redboy and pure Buck/Hollingsworth, I would choose the Buck/Hollingsworth in a NY second ...
I think Machobuck was cleary a Buck dog with the bone density of Mayday. That density came from the Hollingsworth blood IMO, but of course there's no way to say for sure, it's just an opinion.
