Hi -- I am female, play 4.0, both singles and doubles, and play 3-4 times a week. Currently I use 17g natural gut in both mains and crosses, and I string in the mid-point or a pound below the mid-point of the recommended tension range. I hit with some topspin but would like to increase spin potential (without sacrificing power, if possible), so I am considering some sort of poly/gut hybrid stringing. I have not used a poly before, but I am concerned about it being "dead" in feeling and/or being too hard on the arm. So first, are there polys out there that have decent feel and are ok for the arm but still increase spin and don't take away too much power? And if so, what would be suggestions for a poly/17g gut hybrid string job -- i.e., which string in the mains, which in the crosses, what tension adjustments should I make, etc? Thanks in advance for your advice.
