I think the issue with adding weight just at 12 with the 97 310 is that you're not addressing one of the frame's inherent weaknesses, the lack of stability and plowthrough. The lack of spin potential is there, but it isn't like a dense string pattern or anything. I can see exactly why you didn't enjoy it just there and needed to venture out to 3 and 9 as well.
I also get what you're saying about basically replicating the 330 if you have that much lead around the hoop. I played with it in 2 separate set up's with a variety of strings and the best it has felt has been with about 15-16 inches total of lead at 3 and 9 with some lead countering it, so didn't get close to 330...but when you add lead and there is a heavier option, you do think about it.
Interesting that you found some arm tightness with the 330 when you have been accustomed to 335 or so swingweight. The racquet itself isn't very stiff either. I just can't wield a racquet with that kind of pro spec. My strokes aren't solid enough or compact for that matter.
Not too familiar with either of those 2 racquets, but curious to keep up with your VC98 session and what you feel needs to be done to the frame.
Because I'm hyper aware of anything arm related I think I've called a halt to a racket early based on arm tightness. In some cases it has probably just been tight muscles and nothing at all related to tennis elbow, which usually presents as electric shock like episodes in the elbow (for me anyway). The VCORE Pro 97 310 without modification I could absolutely not tolerate. When I tried it a couple of days back in anticipation of the VZONE 98 305 arriving I could literally feel (in a bad way) every single contact on the stringbed.
Anyway... I did manage to get a quick 30 minutes of court time with the 98 305 last night, so just a few observations.
1) I was totally expecting that with mine coming in at a measly 309 SW that it would be completely unstable and unable to deal with a decent incoming serve or groundstroke. Surprisingly, WRONG. The racket felt entirely stable, which I'm actually still astonished by. There is no comparison at all between the 98 305 and Pro 97 310 in this respect.
2) I was struggling with slice backhands and touch shots. For me in its current form this is where I'm feeling the biggest effect of the low SW of the frame. The contact just wasn't as authoritative as it is with a higher SW frame that I'd typically play with.
3) My hitting partner was saying I was getting a god amount of spin. He was saying that balls were kicking off the court, in his words, similar to what he gets from me if I'm using my Angell TC100.
It's definitely a racket that warrants some more time. For me it will necessitate a bit of weight in the hoop to bring the SW up, and counterweighting in the tail to maintain the target balance. I must say, it's also a really nice looking stick, probably one of my top 5 even.
I have an all day tournament tomorrow and being sensible I don't think the 98 305 should come out of the bag. But you never know
I find it to be way more stable than the Vcore Pro 97. My Vcore 98's have a SW of 315 and 319 strung. Added a gram of lead at 12 on the one to match them up.
As above, totally agree. This was the biggest surprise for me. I was expecting the solidity and stability to be compatible between the Pro 97 310 and the 98 305. But they were not in the same class at all, the 98 305 eclipsed it by a massive margin.
Adding weight at 12 will be my first port of call. Simply because it has the biggest contribution to SW with the lowest actual weight increase, and it can also be hidden under the grommets when you've settle on the perfect amount. I did find with the Pro 97 310 that it took weight better at 3/9, so will, be interesting to see if the 98 305 is the same in that respect or not.
