Hi xtc, heard great things about gliss, never used it personally but know that the guys from halco have used it effectively for spinning and jigging, landing big fish in the process. I want to try it out soon.
I have seen a lot of tackle shops in GP have been stocking 4lb nanofil, I love it and its awesome quality. Every now and then you can pick up spools of 6lb rovex viros as well, used the 8lb, 10lb and 20lb and never had any issues except colour fading on the line.
