My goal is lowest possible weight. The K110s are 8 1/4" lbs. apiece. Not too bad! BUT the Tornados are 3.8 lbs. apiece. With them, I'll end up with a 30 lb. cab and be able to carry my head (SMSs + Carvin DCM200L in a Gator 2U, total 17 lbs.), cab, Line 16 M13, and guitar easily in one trip. For other situations, I'll use my FYD + MC50 + 112 w/K120 and 112 w/E120. And if I come to regret the Tornados, no biggie. It'll be a problem money alone can solve. I'll just sell the Tornados and cop some K110s. Look at the positive side - in the interim, you'll have my review.
