I'm currently playing with Wilson BLX Pro Tour but it seems to hurt my elbow. Especially on serves and overheads there is a slight to medium pain on the outer side of my elbow. I haven't had this with my previous racket, so I decided to go back to the previous weight of around 290g unstrung. I've already tried Wilson BLX Six.One Team 18x20... a bit less stable but easier to maneuver (and also because of being 25g less in weight I get tired later), I liked it. If it proves to be too light I can still add lead tapes. Please share your experience and thoughts of elbow problems during serve (yeah, my technique definitely needs improvement) and Wilson 6.1 Team 18x20. Thanks.
