When I first picked up a spey rod 4yrs ago, I was told unanimously to just use a skagit. I stuck with that advice for the most part, getting a scandi head here and there to try out, but ultimately using Skagits for all of my fishing. Recently, I was given a new Delta 7/8 as payment for a website project I did, and I gotta say, I wish I had discovered this sooner! Overall, I think the Delta is a superior style line. Only situations I can think of that a Skagit would be beneficial would be for very heavy flies, big sink tips, or when you have brush right at your back. But really, I rarely ever fish large flies, the type 6 sink in the multi tip Delta will fish most the water I tend to swing, and yesterday I was actually able to use an off shoulder cast to make my cast work out when I had brush at my back. Not only do I find it more enjoyable to cast, but it's a fantastic fishing line. The amount of control I have over my swings and mends is unreal when compared to the heavy shooting head/light running line combo I was used to. I am able to set up swings that used to be very difficult to control. Definitely not jumping in the "skagits are stupid" bandwagon by any means, but I don't think it should be the "go-to" line we tell the newbies to grab. Seems like Skagits have become the default line for most spey guys, but I just don't see the advantages now that I've tried something else. I'm very curious about the Rio UniSpey as well, and plan to give that a whirl soon too.
