lighter weight rackets and poly strings can be the start of elbow problems in the future. The Wilson line, although a bit heavier IMO have better shock absorption on off center hits. Have played an OLDER version of the Surge and have played the Ncode, K6.1, BLX series for several years now and have had no problems with elbow issues. Currently playing the BLX 6.1 with added weight to grip. If you have a high swing speed, go with the lighter rackets, just understand the trade off for lighter rackets is less weight to absorb shock and a solid feel especially when teamed with Polyester strings
