When you say "shot best" or your Ally "loved 66lbs"... Could you explain?

Do you mean the shooter in relation to the poundage?

Or are you saying that 66lbs is the sweet spot of that bow? Kinda like the powerband of a car, while running 55 and flooring it... not much can hang that is stock... but floor it from 70mph.... and you 'might' can get me.. depending on what your in. If that makes sense.... 0-35 and 55-70mph... is my trucks sweet spots. And thats how its gonna be no matter who's driving/shooting.
