Okay, I've just got a Sage 7136 brown IIIe used, but not too. I want to put an Abel on it, Super Series. What size? I believe I'm looking toward a Rio Windcutter 6/7/8 or versa tip (although I am just starting out spey-wise and want to make it a relatively reasonable learning curve). I fish small to medium rivers for steelhead up to 15 pounds... please help.
