I agree with the need for stretch in a reel line 100% Ian,just seems a bit too much to me,but without doubt Sensor is one of a number of good allround lines and if pushed came to shove I would probably use it,my favourite barbel(lead)reel line is Awa Shima Reflector line(18.6lb BS),it actually breaks at 12ish,but the diameter is good,abrasion resistance,knot strength is excellent,garbage for anything else I do,lasts for ages,I have bought 3.4lb and 4.4lb pro-gold to try for my general float fishing,if fishing for carp up to doubles,tench,or slider fishing I use 5.4lb,which I like very much,I use Silstar Matchteam for hooklengths,i've tried it for reel line too and it is good,but it works out expensive at over £5 a 100m spool,reflo is super stretchy,easily damaged,yet weak imo,confidence is key,so if you are confident in any line(hooks too)and your results are good using it,fair play,you certainly shouldn't change...
