Could be because only the 10 and 7 are "real" (for lack of a better term) rackets released in Japan. The 77 and 88 I would suppose are just like all the other low-end rackets introduced only in foreign markets. Like the VT Lite and 0F and NR 300NEO and god knows what. Not saying that's bad or anything, they just tend to go unnoticed because no one really cares about them (on this forum anyway, where most people are racket fetishists and mostly hype top-end rackets).
Ah thanks Okay, that shows there is one that is probably headlight, the duora 7. This guy has barely been released (if even released) and I don't know of anyone who owns one. Nr 750 and 700 aren't top end, the FB is kind of even balance although very light overall. Confident NR900 is headlight
"Nr900 is probably the least headlight=tied with the NRSP" I have no problems whatsoever with solid feeling on NRSP. It definitely has a solid feel, if you hit it correctly. Not that I do enough of the time to properly use it though.
Agreed with xiaqiao, NR900 and NRZS are all head light rackets, it's always advertised as head lights stiff shafts by Yonex Japan. Even the 3U version doesn't feel heavy for me. I own 3 head heavy rackets (ZF,ZF2,80et) and even my feeling and air swing could tell me the difference of head light and head heavy rackets.
For me, NRZS has a good manuverability from the small frame, from my experience using it, swinging it doesn't feel heavy at all, maybe if there is, it's close to even balance, it's nothing compared to head heavy rackets like my ZF2. I definitely wouldn't say it's head heavy.
NR Z speed is very HH. Not as much as ZFII, but still very much so. I can compare it to my Lining n90 I. But the feeling is very different, perhaps it can confuse some.
yeah maybe my feeling tells me it's light or even at max. I love using this racket up front feels like a lightsaber but using ZF2 at the front feels like using an axe , with NRZS the swing feels easy and light with the small frame.
A bit off topic but let me elaborate, NRZS's frame is one size smaller, so manuveribility wise I prefer NRZS for front plays. We play about 8- 10 games of 21 rally points in our club. The first 5 games I'm still fresh , smashing all out and jumping here and there but the latter half I would feel VTZF2 is slowing me down, fatique makes the racket feel sluggish on front plays like too late on net kills and stuffs, smash defense also feels a lot slower. But with NR900 or NRZS seems it could stretch you the whole 2 hours game without having to have too much sore muscles. I had an elbow problem before taking too much underhand forehand side shots using VTZF2 that I switched to my NR900 for a while. I'm actually thinking of getting the new yellow NRZS.^^
...Z speed really isn't that head heavy, it's a tiny bit above even balance on the chart. I call it headlight/even compared to the top end rackets that are available (for li ning, victor and yy). Probable exception is Duora 7, but hardly anyone has even touched that racket. Nanoray 900 remains headlight in my eyes.
Yonex's chart list the Z Speed as more heavy than the VT 80 E-Tune. 900 is about as head heavy as the 80 E-Tune, by the charts.
On the left of the chart it's control(flex), on the right it's repulsion (stiff), not solid feel or soft feel like the chart you provided. I can kinda sense what Yonex UK is about now ;p
I have nrzsp, the bp is 305 and the head weights around 39.x I dont remember the x. It is not head light, almost the same as vt70 in the bp department
