I LOVE my full bed Big Hitter Blue Rough at 45lbs. on my YT Extreme Pro. I noticed a lot of the guys use Gosen OG 16 and 17. How do they compare to 18G? How about hybriding with BHBR vs. BHBR full bed vs. Gosen OG full bed? I'm considering hybrid or full bed Gosen since I have serious tennis elbow, but I'm afraid of losing spin and more importantly, control with syn gut vs. poly.
The most important thing for you to do now is to rest and let your TE heal. That's absolutely crucial. See a PT get some massage, acupuncture and ultrasound. The tendon that inserts into the lateral epicondyle has a very poor blood supply (as do all tendons) which means it takes longer for it to heal than say a muscle tear. Depending on how serious your TE is, you might need a complete break of 3-4 months from tennis. I know its a drag but you need to think long term and do what's best for your body. The worse thing you can do is carry on playing because you're just going to make it worse and increase the problems later on.

As you know I play with BHBR 17 and currently have the following racquets (18x20/95) setup by way of testing, though I'm probably going to settle for 2 racquets with BHBR 17 mains and 1 with BHBR full bed.
1 x BHBR 17 full bed 53lbs
1 x BHBR 17 mains 53lbs / Gosen Micro Natural 17 55lbs (you feel the BHBR mains more with Gosen natural than you do with Gosen white)
1 x Multifeel 17 mains 55lbs / BHBR 17 cross 53lbs
The Multifeel mains is by far the most comfortable. That would be what I would suggest if you still want to stay with BHBR (which is still one of the more comfortable polys) and avoid trampolining full bed multis. BHBR mains is still likely to be a problem if you have TE.
Full bed Gosen 17 works as well (57lbs in a 18x20/95) and will give you depth control, but if you have serious TE, you'll probably still find that uncomfortable at mid tensions. Gosen Micro Natural 17 is softer than Gosen Micro White 17 by the way but is less crisp and slightly more springy.
Hope you get better and make sure you REST!!!
