After I switched to the Pro Kennex Ki 5x, my elbow improved and my game improved, largely because I was free to swing away like I did when I was younger. The arm-friendliest racquets I tried were:
Prince EXO3 Tour 100 (most comfortable)
Volkyl Organix 10 325 (next most comfortable)
Pacific X Force Pro
Pro Kennex Ki 5, Ki 5x, and Ki 5 PSE
I suspect that the other racquets in SystemicAnomaly's list are arm-friendly as well. The Ki 5x was actually the least comfortable of all the racquets on the list that I tested, but it fit my game the best, and it was certainly much easier on my arm than the Babolat Cortex racquets I owned.
+1, cortex is a marketing gimmick.
