In all honesty, I haven't tried them yet, I have a set I'm going to put on my SR4 but have yet to do so. From what I've read, somewhere in between TI and Rotos. I'll let you know after I string it up.
lmfreeman9, I put a set on my SR4 last night. Not as high tension as a Roto 77 45-105 set, but definitely tighter than the GHS Flea Sig 45-105 set they replaced.
shawshank72, pm sent, I've got one set on hold for you. One set remains.
