Peter's thesis on GL lines
This is part of the reason that I ordered the multi-segment mid-spey for my new rod. I thought of doing that the last time I bought a spey line, but I was talked out of it. But looking at what you can do in terms of removing the front segments, it seemed to me that in many situations, being able to remove the front tapered ends and then attaching a sinking leader/head/tip makes much more sense for many of the situations GL fishing calls for. Also, replacing the front two segments with a single intermediate segment and then a sinking leader/tip/whatever could, I'm guessing, be useful in some situations.
