Hi guys, I'm an intermediate - advance player, just like to ask for opinion here, I recently plan to buy another racket, broke all my pasts racket so I stopped buying for a few years.

Recently Tan Boon Heong have a collaboration with Li-Ning brand, so I plan to buy the racket in 3U. It's medium flex + head heavy, I'm thinking of buying 3U and use it for doubles, I would say my wrist got the power for it, but still is it do-able using 3U in doubles ? Would appreciate advice.

no issue at all. i use arcsaber11th 3u and play doubles only. pair it with thicker & less repulsive strings like bg65ti.
tried few 4u, just not for me. too light

Glad to hear that. By the way any chance u happen to know, does stencil ink like Yonex / Li-Ning logo affects the string ? Heard from some people that says it might cause early breakage of the string, or for example Yonex's logo would cover the sweet spot etc.

duno. nvr used. no need to tell ppl what brand i'm using, from far away
lol

Start with even balance 3u racquet 1st like arcsaber 11 then switch to head heavy 1
