I have that exact same Nokona in Walnut - I love that glove. Unfortunately after 2 hard seasons, the leather is getting too floppy for me. If you're going to play hard, I can tell you right now the Nokona Walnut will go floppy on you. If you like the fingers in your gloves to stay stiff, you'll have to look elsewhere.
And it kills me to say that because I love the Nokona company.
As for me, once you go PRO12TC, you never go back.

And the ones Don Morton has are a nice stiff leather that don't say "oil-treated" on them. I don't know if they are oil-treated or not, but they're stiffer than other oil-treated HOH gloves I try on.
