I found 10 pound and 20 pound Spiderline at our local Spiderline emporium. The 10lb is a bit larger in dia than .008" steel to the eye but almost imperceeptibly so - and it is not really round in cross section when you look at it up close anyway. But it "measures" about .009" or so. The 20lb measures about .012", which with the crude measuring makes sense since one should be 1.414 times the other.

I measured off two 35 and two 42 foot line sets from the 20lb but have not flown it yet. I expect it to be a bit draggier than .008" steel obviously, far less draggy than dacron crap, and tough enough for many sport flying sessions. This is one of those rare cases where not being kinky is a positive personality trait.

The 10lb will take a bit more care, just like the .008" steel but I doubt anywhere near as much a PITA. It is a ***** to tie a knot in though - and slippery enough to untie itself through all the basic knots. I have good success in break tests by tying off 2-3 half hitches, then carefully melting the loose end in a clear little ball with radiant heat from a nearby Bic (not charred and infected looking).
