1. SigPro Tornado (textured) or Hyperion (smooth)
2. Tecnifibre Blackcode (textured) or Redcode (smooth)
I play SigPro - really seem like good quality and you can get the price in the $8-$10 range if you buy a reel and are careful about lengths.
I also hybrid which seems to add a bit to poly life span. Currently, syn gut or multi mains with poly crosses but have also used poly mains with syn gut or multi crosses.
