There's no way for me to answer your question if you don't answer mine about how and where precisely you've put weight on your current racquet. The weight means nothing without the repartition. Where the weight is matters way more than how much weight there is. If you put 25 out of 30 grams in the handle, the racquet you have will play nothing like the 97 or the 97S. Nothing at all. And if you use either one of the repartitions I've put in my previous post, your 97LS will feel heftier than the 97 or the 97S.
EDIT: Also, if you have your eyes set on two racquets, the best way to determine which one you like more is to demo, and you should demo. TW and TW Europe both have pretty good demo programs depending of where you live. Both could work for different reasons: the 97S for the more similar string pattern, and the 97 for the more similar mould (while not identical).
I don't have my eyes set on 2 racquets, I just mentioned those 2 going off of popular opinion.
The weight is in the 3 and 9 o'clock positions in the racquet, and I'm sure the extra grips add to the weight to.
So what racquet do you think would answer my original question here, which was:
Hey guys, I'm currently using the black Pro Staff 97LS. I'm looking to upgrade now to a, well a big boy racquet haha.
I'm looking for a heavier racquet with a similar feel that does all that the 97LS does, only better.
I'm 23 YO, and use an eastern single handed backhand, and a semi western forehand. I currently have lead tape on the 3 and 9 o'clock positions, and I've Richard Gasquet-ed my grip, so the racquet weighs around 336g. I've been using lead tape, but I want a racquet that carries that weight already. Lead tape is fine, but I'm missing the heft from an already heavy frame if that makes sense?
Any suggestions for a racquet that fits my billing?
The most popular suggestion seems to be the 97S
