Ok, long post for measly 19.5 feet of string: I'm stringing Hybrid Kirschbaum Comp 1.25 mains with Gosen OG Sheep Micro 17 crosses, and have been looking for a softer, more powerful replacement for the Gosen string. I had a set of Iso-Speed professional 17 lying around and strung up a racquet with that and fell in love with it. Great balance of control, power and comfort - exactly what I was looking for. As luck would have it, TW stopped selling the Iso-Speed Pro, and no U.S. retailer seems to carry the reels of it (I string myself, so reels make a lot more sense) When I looked for a replacement in the vicinity of the Iso-speed Pro on http://www.racquetsportsindustry.com/issues/200609/200609stringselector.html all I can seem to find is head strings that come as part of Hybrids or strings that most retailers don't carry. So now I'm looking for recommendations for the sub-10$ sets that are available as reels with similar power and comfort characteristics to the Iso-Speed Po with more durability - any ideas?
