Thanks for the help fellas. I'll see if I can find an echo dealer and try one out. Interesting comment on the head length as my issue constantly was if I was not right dialed in timing-wise, the rod would "fold-up". When I hit the timing right, set my anchor where it was supposed to be and kept the curve moving, it would fairly fly out. I did find I could shoot about 20 feet beyond the head with the double left. Felt much more comfortable with the double on both sides than the single on either.
I've been fly fishing for almost 40 years and this is just plain starting over. I can certainly see the efficacy of this method in a lot of places, but damn, atlantic salmon fishing is pricey.
