Ok, here goes. I have three SDC blades, all three very similar.
All have a conical handle that, to me, is the pinnacle of perfection; an inner composite composition, with all of them having a Kiri core, and a Black Limba second layer; and a low balance. In terms of build and finish quality, Sergio's work is just top notch craftsmanship.
Blade 1 has a Black Walnut (US Walnut) outer, and an Innegra Carbon 3rd/5th layer. Just over 90g, resonates at 1356Hz, balanced at 2.5cm. It's a spinners blade, immensely stable, playing pretty much like an all-wood blade. Very enjoyable, and it let me play a two-winged spin game pretty much faultless. However, I did get overpowered, even when hitting all-out; which made me think a tweak towards an increased top-end speed would be nice.
Blade 2 is like blade 1, with with EU Walnut instead, weighing 95.7g and clocking 1356Hz (identical). Balanced a tad lower, 2.4cm. Even more an all-out spinners blade, chewing up and spitting out the ball pretty similar to #1, but with a bit more punch at the high end but still quite enough to finish the point at times. A bit unexpectedly: also slightly less suitable for direct hits - counters and smashes, really nudging towards a spin everyting approach. Which is fine, but also a bit demanding and sometimes I thought it a bit too demanding for an aging player like me. Even Istvan Jonyer and Ryu Seung Min couldn't keep that up, in the end; time to accept that.
Blade 3 has Koto outers and AC# composite, weighs 93.7g, sings at 1464Hz, balances at 2.4cm. It has a higher top end speed, with it power gradually engaging; a bit less springy, and a very dependable power curve. Still offering a deep hold and great spin, but also very capable of aggressive blocks, counters, and smashes. I'm playing with it now, using #1 and #2 as backup blades.
