Has anyone tried this? After comparing multiple polys, I've determined that the difference between gut crosses vs. synth gut crosses is considerable for me. The gut makes it much more comfortable and more pop. Standard multifiber synthetic guts don't feel that great as a cross for me...worse than a solid core synth gut. So I'm trying to see if there is something cheaper than gut but has similar shock absorbing qualities to use as a cross...the Isospeed strings look like a promising solution...anyone have any experience with this?
