Yeah those T-90s are pretty nice. I still have my set and shoot with them fairly often. I think they had like ½ dozen or so barrel finishes, I ended up ordering a set ringed ones, where I usually prefer a fairly heavily knurled finish like on the Strikers, which I also have a set of and still use fairly often, and especially on the Bottelsen Heavy Metals. On my T-90s, all the rings are at the top portion where the shaft threads in, and the rest of the barrel all the way down to the end is plain, save for two fine cut rings way down at the end. To be honest, I'm not really sure why I even ordered them at all, and I know they had knurled finish, but for some reason I ordered outside of my normal comfort range. I also have a set of ST90s that are ringed, although those rings go further down the barrel toward the point. Funny how those 80% Strikers are among my favorites despite the fact that they cost me ½ as much as my T-90s, and less than ⅓ of many other other sets out there. One particular set of Unicorns that I really liked and still use are the Sparks, 80%, steel point, blue 24g. Another one out of my comfort zone, they're ringed also, but a more aggressive cut and they run the entire length of the barrel.
