Stihl Strimmer Line

[SteveW1000]

I run a volunteer project in East London working on a number of ecology sites and use seven stihl strimmers using stihl square 2.4 and 2.7mm line.  Saw the fancy new line in last years catalogue.  My dealer doesn't carry it so phoned stihl asking whether they could send me a few metres to try, no you have to get your dealer to ask the rep.  Have thought about emailing Stihl Germany for some, get the impression that this is par for the course from stihl uk.  Anybody used the triple layer line is it worth trying to get a sample?
