I don't think you'll hear many people complain about EZSoy (unless they are anti-Soy). It's pretty popular (and popular for a reason!). Are you curing them for a week? Also, I'd try using 1oz of FO's from Peaks, BitterCreek, Candle Cocoon, Just Scents, or the Scented Bean. They are tried and true and also loved by many. Look in the classified and you'll find samples for sale. The Scented Bean has a great sampler package as well. Try adding your FO at 170ish then stir stir stir. Cure for a week and then take a sniff.
