Hi Steve - can I ask which circumstances?
I must say I'm tying myself in knots on this whole line issue. I've been using braid for trotting and legering on the Kennet, but I'm never sure whther I prefer it or mono. I use fourocarbon as a hooklength religously when fly fishing, but not when trotting. I feel that when trotting or legering I need stretch when using braid so a mono bottom is best, but I like the properties of Flouro as a hooklength. I don't use braid hooklength when legering and never hair rig or anything. I occasionally use mono for trotting, or laying on etc. but use Daiwa. The whole thing has ciome aboyut since I witnessed my line spook chub and trout last summer. On most occasions it was fireline, but that'sbecause I normally use fioreline. I have tried spiderwire in camo, and I'm quite pleased with it but only for winter legering so it's an unfair test.
The main reasons are that in much of my fishing, such at Wingham, I need high abrasion resistance. From the lab tests I've seen there's a huge variability in abrasion resistance with monos, much less with fluorocarbons. From this it seems that you can get higher abrasion resistance from monos.
Secondly, all the fluorocarbons I've handled have been stiffer and lacked suppleness compared with mono.
Thirdly, fluorocarbon is a lot more expensive.
Fluorocarbon technology is relatively new and so I'll keep an ear to the ground. In the the meantime I'll stick to using fluorocarbon for hooklengths in special circumstances such as when I want extra stiffness, such as livebaiting for perch to reduce the risk of tangles. I also find this stiffness of use for paternoster links for the same reason.
By the way, Mike, the lab tests showed that the amount of stretch in monos and fluorocarbons was broadly similar.
