Sounds like the BK II is what you need. You really can't appreciate how fast it is until you shoot it, it stores quite a little energy, ie a really long power stroke, don't creep it. I think it weighs just under four pounds and is easy to shoot with the short brace height. I was worried about that but have had no trouble controlling mine, since I got properly spined arrows. I have the 6.5 inch brace height and it shoots like a dream. You better own a fletching jig if you are not shooting a five spot target.
