Not sure if anyone can explain why this happens, but I have noticed when you increase SW on a platform type of racket by adding short strips (4 inches of 1/4 lead tape) @ 12 the stability seems to decrease.
When I first started customizing, I was playing with a DR 98 (stock twistweight =13.69) in stock form but once I added 4g of lead @ noon I found myself shanking/hitting off center more. I had to add additional lead at 3 & 9 to bring the stability back to what it was originally in stock form.
I did a google search on this and found this thread from a while back > https://tt.tennis-warehouse.com/ind...-reduce-twist-weight-by-adding-weight.623065/
Basically the consensus from that thread was that you can't decrease stability by adding weight to the frame and that made perfect sense to me, but on court it doesn't seem to work that way.
Now of course some rackets come with a ridiculously high twistweight so this doesn't really apply there, this is more so talking about platform type of rackets (DR 98, Vcore 95, Ultra Tour 97, etc...) and the effects of increasing SW by 10-20 pts.
My theory is that for a certain SW you need a certain amount of twistweight otherwise the racket will be unstable. For example you could theoretically add 10g @ 12 to a stock racket and increase the SW from 320>350 but it most likely won't be useful because you can't really tap into the power of a high SW frame with a low twistweight.
TLDR;
1. If you increase the SW past a certain point you will need to add additional twistweight
2. SW needs to be considered in relation to other specs of the frame (twistweight, balance, static weight)
I would love to hear some more thoughts from @travlerajm or any other people who have thoughts on this...
