Hi Bruce, thanks for writing in. I'd be happy to assist you in identifying the right channel balance. First I'd like to verify some information. Can you tell me the exact width of that bottom shoe? It's a little hard to tell in the picture. Take a look at the picture below to see how we measure this part.
