Okay, I went back and read your first post again. You asked a question related to "responsiveness" but don't actually discribe what you want to achieve other than "...when I pushed on the pedals hard there was an imediate reaction from the bike". What kind of reaction did you experience? I assume you are talking about bottom bracket stiffness but frankly you are pretty vague in your description. You also mention something about raising the front end of the bike so maybe you are looking for something with a rear weight balance bias?

My guess is that a frame with short chain stays (for rear weight bias) and a stiff bottom bracket might be what you are looking for. Just a guess though based on your description.
