Yonex Polytour Pro 115 Blue

One of the best soft poly's out there

If you have elbow issues, but still want to play with a poly; this string is what you're looking for. These are probably the best softer strings you can get that isn't a multi-fil or gut. Several pro's use these in their crosses in a hybrid setup or a full bed. There's a reason, they feel really good and give very good feedback without aggravating elbow/arm issues. You can string these at a lower tension if you want too (<50lbs) and still feel like you can control the ball and get power out of them. They are a smoother string, I've see reviews that say they "can bite into the ball" ... you guys are having a laugh. If you're desperate for spin these aren't for you - but it's not difficult to get spin out of this.
