All good advice, and so true. The string being of lighter weight will produce in most cases faster speeds. The old models used a safer material that would help the bow survive a dry fire. When the Matrix series came along, they were already equipped with a string made from performance materials, and the safety factor was gone. There are several performance materials used by the folks here ranging from D97 to Force 10, and others as well. Most string makers dabble with stuff to find what they like on their bows, then test it, then get others to test them, etc. Boo has been at this a long time, and knows a lot about the various materials available, and has shared a lot of information to others, myself included. VixenMaster, 8ptbuk, nchunter, Keith also have been twisting their magic for a few years, and have perfected their technique. Danny Miller makes more strings than anyone on the planet, and makes a damn good string. All that said, i would be happy to twist you one up to use until you get one from someone that makes you one better. It would be on me. If you could get one of Comfybear's (Lou) strings, you would also be one happy camper. PM me if you want one, and give me a few days to git her done! Most colors in stock, so pick a couple, or let me do that! On me, including shipping! This is more of a hobby for me these days, so you can be critical of my work if it makes you smile.
