I've been dealing with Weaver for well over 10 years now but lately the Hermann Oak sides they sell me are very bad. The last one that came in convenced me to try out another vender for HO because I only was able to get about 30% yield out of it. Weaver makes and sells there own line of leather products and I'm sure the products they make are made from the good stuf. They sell HO as tannery run (A,B,C). Lately all I seem to get are the C's.
