SMR, ya man, you got it. Windcutter 5/6 for the 5120 IMHO.
Gary W and JGS,
Let me explain way i like to fish the little two hander for trout. I have fished for a long time and guided for the past 10 years for trout and although i still like to fish the spring creeks sight fishing with dries I am tired of blind fishing with large attractors and such. Here in the Rocky Mountains we have large rivers and a common way to fish them is to explore the water with a huge foam dry fly and a bead head dropper dangling below. Nothing wrong with that except that I am tired of it. I get to stare at big dries long enough while guiding. So when it is my time to fish I go looking for steelhead partly because I really enjoy two handed casting. Well, i can't always make it to a steelhead river. When I can't, i shed the huge pack that i wear while guiding equipped with a full fly shop inside and instead carry one spool of 4X and a small box of soft hackles, that's it. I would rather swing soft hackles and not catch fish then catch 50 trout while blind fishing with a mega foam thingy fly. What happened is that my friends and I started to catch fish, sometimes just one or two and sometimes the soft hackles actually out produced all other methods, which surprised me. So then we started experimenting with times of the year and hatches and are still experimenting with fly patterns and swing speed. THE TUG IS THE DRUG! And the bonus....it is perfect for spey casting. Do I always use the 12 footer? No. More often I use(spey cast) a 8 1/2 foot 4 or 5 wt. But when the water is big enough, I like to use TWO HANDS.
Right now for example, our rivers have great midge hatches and the fish are rising all through the middle of the day. You can fish dries, very fun and some what challenging because the dead drift has to be perfect and in an area the size of a coffee cup. Of course it is hard to see the tiny bugs and you really have to pay attention. As I said above, I get plenty of time to pay attention, so now I would rather swing a Syl's midge (Sylvester Nemes)trough the riffle or pool and wait for the tug, watch the boil, the line tightens up and the "Perfect" sings. Why do the trout eat a size 16 soft hackle on the swing when the natural emergers are 22's? I do not know. I am just glad that they do.
