I'm getting to the end of my Pro Supex Big Ace Micro reel & although I would love to reorder more of the same, I'm thinking that I should probably move to something else. I love the way this string plays! It has tons of pop and feel. I find it to be the ideal string for an all-courter, since it provides a lot of control from the baseline and plenty of feel from the net. Unfortunately I'm having two problems with this string (at least I think I am): 1) I'm breaking it like crazy. Yesterday I broke strings in 3 racquets. My strokes are improving & I'm hitting the ball harder & better than ever. When I was experimenting with strings I was tesing out almost all 17g's & I found the BA 17 to last much longer than anything else that I had tried. Since it lasted so long, I gave the Micro a try once it was released & I found it to last longer than the Topspin Cyber Power 17g that I was using at the time. I also liked the way that it played more than the CP 17, so I went ahead & ordered a reel. I suppose that I could try out the 18g BA, but I probably shouldn't because of problem #2. 2) I'm in the proccess of trying to change my service motion. Of course making changes means that discomfort is inevitable. My arm, from my elbow to my shoulder have been in a bit of pain due to poor timing & flawed mechanics. I know that this is probably going to go on for a while, since the serve is such a labor intensive stroke to renovate. I'm thinking that maybe I should switch to something more forgiving than a poly for the time being. Anyone have any thoughts or suggestions?
