Alright, I'm considering replacing a couple of my sinking lines for 2014. It looks like the current crop from Rio and Airflo are pushing the idea of low-stretch for better sensitivity and hook sets. I've seen these new products mentioned in a few threads. Is there any weight to these claims? I don't buy new lines very often so I'm willing to invest knowing that I'll be getting 5+ years service. I'm specifically looking at a fast intermediate (+/- 2 ips) and a super fast sinker (ala Deep 7). The lines I'm replacing were both purchased in 2004 when new lines cost $50. I fished them both this past fall and they still work . . .but are showing various examples of wear and tear: discoloration, splitting/cracking, nicks, permanent kinks, etc. If the new less stretchy lines aren't a significant improvement, I'll start looking for closeouts on NOS.
