I've been trying to customize my Blade V7 16x19 for a bit more power and stability, while also creating a head light balance with some tail weighting. But it's getting club-y and it feels like I'm fighting the DNA of the Blade. Is it possible to have a head light racket with good stability/power that doesn't weigh as much as the RF97?
If you want a head-light, maneuverable feel then the Blade is the wrong starting point. The Blade series is known for being relatively light with lots of mass in the head for a high swingweight. If the RF97 is too heavy, why not look at the regular PS 97? The new v13 is supposed to be pretty good, and 315g is still pretty solid by today's standards. Sticking with a 98" head you could also look a the Volkl C10 Pro. Finally, the new G360+ Radical Pro has been getting good reviews. I haven't tried that one yet and it's not super head light, but the reviewers all mentioned surprising maneuverability for the specs. If you want to go extra-stable, the Yonex VCORE Pro 97 330g sounds intimidating, but I've played it and it's faster and easier to handle than the weight spec suggests. It's still easier to use than the RF97.
For a really off-the-wall solution, the Phantom 93P (either string pattern) is surprisingly maneuverable for its hefty static weight due to the thin beam, small head size, and HL balance. As much as I like Prince, they seem to be unable to make a good 97 or 98" option, so you would have to look at the Textreme Tour 95 or 100P for more mainstream options in their lineup. The Textreme Tours that I've tried have all been very solid and maneuverable.
This is a long list, but there are a lot of good racquets out there. The only one someone might mention that I would avoid is the Yonex EZONE 98 Tour. That one feels very Blade-like in its balance and swing.
