The reference point
The source review immediately compares Kumpoo Shanhai NEW with the Yonex Arcsaber 11 Pro because the frame language is similar: full fluid box frame, balanced-control intent, and a big enough face to invite all-round play. But the on-court behavior is not a clone. The 11 Pro has a clearer whip sensation through the second half of the swing. Shanhai NEW feels more even through the whole motion: steadier, heavier, and less springy.
Measured setup
The review sample was 4U/G5, strung and overgripped without the base grip at 88.23g, with a 308mm balance point, 35 lb warranty tension, 205mm handle, and 215mm shaft. String was Yonex EXBOLT 65 at 25-27 lb with prestretch. That setup matters because it explains the reviewer's main theme: this is not a featherweight speed frame. It has enough mass and balance to feel composed, especially in singles patterns and patient build-up rallies.
Hit feel
Shanhai NEW hits firm and stable. The 6.8mm shaft and rigid frame resist twisting, so the face stays honest through guided clears, pushes, and controlled transition shots. The tradeoff is that the racket gives less free launch than an elastic control racket. If you want deep clears, you still need to add active force. If you do, the payoff is accurate, low-noise response with very little frame wobble.
Where it wins
Control is the clean win. The source review specifically likes tight net exchanges, short placements, and patient back-court control. Heavy smashes are also better than the Arcsaber comparison might imply: the shuttle may not leave at extreme speed, but it carries enough weight that opponents struggle to lift cleanly. This makes Shanhai NEW useful for singles players who build rallies through length, pressure, and one decisive finish rather than constant early attack.
Where it loses
Flat drives and first-step racket speed are the concern. The reviewer's long-term use of lighter 5U and low-swing-weight rackets made Shanhai NEW feel slower in quick exchanges. The frame is stiff enough that the shuttle leaves cleanly once contact happens, but getting the racket to the contact point takes more work than with pure speed frames. Fast doubles specialists should take that seriously.
Stringing and buyer fit
The source review recommends harder elastic or attack strings rather than thick 0.70mm durability strings, which can make the setup feel too meaty. Buy Shanhai NEW if you want a balanced racket with high stability, controlled singles behavior, and a heavier ball than the Arcsaber-style comparison suggests. Skip it if your main priority is fast doubles interception or ultra-easy lift assistance.
