Phil - W/C just started selling the Tooling/Holster in shoulders so call them. They average around 13 s/ft.
On the other hand until the end of the month they have a sale on T & H sides in russet (aka natural) for a flat $90.00 plus S/H. I just got some of them and they were real nice with clean backs and averaged $3.25 a s/ft since they were all 25-27 s/ft/
As Paul noted grading is fairly subjective by tannery/dealer, but is generally based on how clean and free of range marks (scratches, etc) and brands the face is, plus how clean the back is........
I usually deal with Glen Proud at ext 222 when he's around (seems like Paul calls him too) or Matt Bressler at ext 216 - all the folks ar nice there though.....
Imported hides are not "bad" per se - I've had good ones in the past, but it's more hit and miss as to quality and over the last few years mostly miss - plus by buying W & C or Herman Oak you're supporting two of the last three tanneries left in the USA....Weaver does sell Herman Oak, but Herman Oak is much "harder" than W & C - that can be a blessing to some......on the other hand W & C will double or triple plate any hide you want at no extra charge last time I asked....this makes the hide firmer, which can be good for some uses but makes it tougher to work - 98% of the time I just don't need that extra firmness.......
Hope this helps...
