I've been experimenting heavily with customizing various frames. I got a hold of Mantis PRO 295 and I did a polarized setup and added a lot of weight at the base and top loop of the frame for around 12oz total.
The result was ridiculous head speeds at almost zero effort. I just start the stroke and the racket just flies from there, given I relax my arm and let it. In match I can just relax and let the racket fly instead of trying to add something right before the impact. I've done polarization setups before but nothing swung quite like this. I couldn't tame PRO's open stringbed, but that's a second issue.
I've tried to replicate this in some of my other rackets, Ezone xi98 and Bio 300 and what I find is getting result like this requires VERY careful weight adjustments - a gram too much and the load up gets a bit slow, a gram too little and the racket doesn't carry through the stroke optimally.
So I find that swingweight is not really the defining factor, but rather swing weight for particular weight distribution.
