first of all...did the racket that you tried have the same string as your n6.1? you can definitely make your racket play softer (unless you're already using gut).
and secondly:
Ive looked at some new racquets since my game was off.
you're looking to exchange rackets just for
THIS?! one of the board member's signatures states something very close to "losers find an excuse to lose...winners find a reason to win." from what you've said already, you're blaming your racket for the exact reason that YOU are not playing as well as you did before.
3rd. if the n6.1 does not feel solid...then i doubt any other player's rackets will feel solid. n6.1s are very stable...stiff..but stable, which can only mean that you're not hitting the ball correctly on the sweetspot. also, assuming that you're switching to a MP, the headsize difference won't make too much of a difference from the 95 sq in. on your n6.1.
i hope i've made my point. im not trying to attack you personally or anything like that...im just trying to prove that you cant just blame your racket for not being able to play well unless you couldnt play well the entire time you have had that racket. i would save the hassle and the time and money and just correct your form. hit against the wall, have someone analyze you, try to think what you are doing wrong...anything basically to improve your game from the slump..because believe me, everyone has their slumps, even federer..although his slumps are more like a "decent day"
