Rack-Atack,Your loseing 6 fps. ??.WOW, Thats alittle high.I have found that I only lose 3 fps.,and thats with leeches on the cables as well.
There should' nt be any reason to serve them in, as long as your string has twists in it,wich I' m sure it does.The trick to " long life" for your leeches is to make sure you have them as far down the string as you can get them.Thats on BOTH ends.
They might not be as " effective" but on my SQ2 I can' t notice a differance,,and they last ALOT longer[:-]
