It sounds like your really trying to nail down that magic window and sometimes it can be really difficult. If Shh-Pat isn't working for you, I would suggest looking into Happiest Baby on the Block, by Harvey Karp. His methods are in line with Tracy's and his technique is very similar, just a slightly different positioning. It worked like a charm for my DS1. His book is recommended in our resources section but I would either get his DVD from the library, buy it on line or search him on Youtube.
For more specific advice, it would be great to see your EASY and then we can try to help you out.
