That's a good idea, although beware the rabbit hole you're going to be diving into
.
Also, if you're not looking to match any particular racket(s) right now, then unlike
@esm, I would actually suggest going in blind (i.e. not measuring your current racket) and working everything off of delta so you don't bias yourself to anything you read on the forums or anywhere else (e.g. trying to replicate a pro's spec. or that someone somewhere posts that a 21.3 mgri is the most optimal setup etc. etc.).
And by delta, I mean by simply recording the adjustments you make (i.e. +2g 12o'clock, +4g buttcap etc.) and not aiming for any particular spec (i.e. trying to get 4pts HL, 335 swingweight etc.)
You'll obviously need to start somewhere, and your starting points can either be:
Mass : Lead at the throat, increases static weight, but shouldn't make too much difference to swingweight or balance.
Swingweight : Lead at 12 o'clock and the buttcap, should increase swingweight, static weight but not balance (roughly at a ratio of 1:1.5 12 o'clock:buttcap)
Balance : Lead at just 12 o'clock for swingweight and more head heavy. Lead just at the buttcap/handle for more headlight.
Just keep a log of what adjustments you've made, what you liked about it, what you didn't etc. and then you can try to shore them up in the next round of tinkering.
