I bought one of these blades as a backup for my Rosewood NCT V. It feels pretty similar, but not exactly the same. With both of these blades I used tacky Chinese rubbers (Hurricane, Skyline, Xuperman). I left a review of Rosewood NCT V
here.
I'm somewhat of a connoisseur of 5-ply outer-hardwood blades. I've used both NCT V and XO models for ~6 months now, and I used Ma Lin Extra Offensive for several years. I've also tried Ebenholz, Emerald, Arctic Wood, Nostalgic, Goiabao, and Offensive Classic. All of these blades have a 5-ply composition of:
hardwood - spruce - ayous - spruce - hardwood
where the type of hardwood varies with the blade. The Rosewood blades use rosewood, Ebenholz and Emerald use ebony wood, Ma Lin Extra Offensive uses walnut wood, etc.
Based on my experience, the characteristic of Rosewood that sets it apart from the other 5-ply outer-hardwood blades is that Rosewood has an extremely nonlinear response to force -- when you hit the ball hard you get a sharp cracking sound and a very fast ball, but if you hit the ball softly you can place the ball very short on the table.
Compared to the NCT V, the rosewood in the XO model feels more muted in its effect. XO feels softer and more flexible, and has more of a linear response compared to NCT V. You still get some "pop" when hitting the ball hard, but not as much. This results in better control and lower throw angle, but you have to provide more of the power on your own. In terms of feeling, this feels somewhere between Ma Lin Extra Offensive and Rosewood NCT V.
Looping is more stable with XO, but flicking and slapping is more powerful with NCT V. As such, XO is more suitable for playing loops far from the table. NCT V is more suitable for attacking close to the table.
