Hello, I have a 88d 99lcw (4u) and I mostly play doubles for my club. I bought a LDF 4U4 and I'm afraid that the grip might be too big for me (haven't tried it on court yet and it's still stringing at the shop). Someone offered me a duora 10lcw for a reasonable price. I wonder is 3u too heavy for doubles? Should I choose 88s 4u? Any other recommendations? Note: 1) I'm not finding my rackets insufficient but just wanna try something new. 2) I've played with 100zz but sold it to a friend. 100zz is also okay but I prefer 99 over it.
D10 is quite even balanced so you won't have any issues using it even though it's 3U. It'll probably feel faster than your 88D/99.
