Customizing 2 rackets of 4 gram weight difference

[thelimfactor]

To all the racket customizing aficionados here, hoping you can kindly assist.

Background: 2 rackets, same make and model.

Racket A is 4 grams heavier than Racket B from manufacturer.

Customization:
Racket A: 5 grams of lead weight at 3 and 9 o'clock.

Racket B: 7 grams of lead weight at 3 and 9 o'clock (2 additional grams of lead each side to make up for overall 4 gram weight difference).

After adding these respective lead weights both rackets are now exactly same weight, same swingweight, and same balance point.

Questions:
1. Will the extra 2 grams at 3 and 9 o'clock of racket B be very noticeable compared with racket A on hitting? (Yet to take it onto the court to trial). Will this change twist weight much? and will it be noticeable?
2. For racket B is it any benefit of moving the 2 gram lead weight difference (compared to racket A) each side and move some to the tip of the racket while counter balancing by moving some to the butt of the racket (to preserve balance point). This way if both rackets have 5 g at 3 and 9 oclock then twistweight should be identical.
3. Should I be concerned that extra 2 grams of lead each side of racket B will change playability?

Any thoughts, suggestions or comments would be greatly appreciated. Really thankful for the huge knowledge base here on this forum. Cheers

If you move the two grams say at 12oclock your swingweight will shoot up by about
6-7sw points. I notice 4gr extra total at 3 and 9 when modding. Feels more solid in volleys less twisting but can be cumbersome too. 2gr total you may not even notice. You could also put the 2gr in the throat which won't affect things much. Try it out first! You have matched frames.. try them both!!

Thanks for your learned thoughts. Appreciated.

I like the idea of putting it around the throat area. What will be interesting is to see if this matches where the inherent manufactured 4 grams heavier weight of racket A is.

Just a thought though if moving the additional 2 grams of weight each side from 3 and 9 o'clock (total 4 grams) on racket B to its throat, would I have to put eg. 1 gram at the tip and say 3 gram in the throat so that this preserves the swingweight, beacuse if all 4 grams was at the throat may this reduce the swingweight a little...in theory?

Yeah you will have to tinker to get the SW right. If that is your goal. Use the TWU university tool it will tell you exactly or close to where to put the lead.
Honestly if you have matched frames and same string, try it first. Go by feel rather than numbers. Sounds like you know what you want

Cheers mate. Thanks for the timely response.

Thanks for pointing me to the TWU calculator. Just tried it- What a helpful tool it is.
