The Tecnifibre syn gut isn't that great, i'd stick with forten sweet, prince syn gut, or gosen OG-sheep.
The polys are reversed, polyspin is a basic, solid performer, and polylon has this weird feel to it. Some people LOVE it, some people HATE it. I'm kind of in between, it has a pretty consistent feel, but the feel itself is kind of weird.
I prefer polyspin over the polylon, buti feel the polylon is a more consistent performer.
