I have a pair of yukons now and I just ordered the lowa tibet ll yesterday. I will soon own both and be able to tell more soon. I like the yukons but after breaking them in they are slightly too big. The yukon is a medium stiff hiking boot while the tibet is supposed to be a stiffer backpacking boot. When I put my pack on and went to my Florida hill , lol, I found the limits of support in my yukons. On steep side of the hill , an eroding ancient sand dune, the boot flexed over and just lost it. The fact that they are a half size too big didn't help either. Hanwag has not imported the new leather lined Ancash boot so I decided to try the Lowa Tibet leather lined. The Tibets should be stiffer . I believe the Lowa Baffin Pro boots are being discontinued and replaced by the Tibet LL . They trimmed a little weight and changed the color is all I can tell. I got the Tibet LL for $262 to my door so I couldn't pass them up. The Yukons are a very nice boot if you are not loaded up heavy and I got them for $154 so I can't complain. I just wish I had discovered the size issue before STP sold out of them.
