I use Sword VSea and have comparison to many other blades, also Sword HD Long5, DHS Long5 and Butterfly Innerforce ALC and Harimoto.
As I know, VectranCarbon is same material as ArylateCarbon. In therm of hardness and feeling, Sword VSea is somewere between Innerforce ALC and Innerforce ZLC. My blade 92g is rather hard and stiff, but not too much. Indeed there is no noticable catapult, what is noticable for Sword HD Long5. Catalult I call the effect of springness from the blade, what makes shots more effortless, but less controlable in low gears. Sword VSea is very lineral, fast when you play hard, but control is very good for soft shots. The best feature of this blade is feeling of stability. Very large sweetspot and solid feeling gives you a lot of confidence. The blade is very direct, so active block is very easy, and counterloops are just insane, especialy with Pinyin Cuifeng Bluesponge you want to counterattack every loop.
The disadvantage for me is that the prints come off quickly after few rubbers changing. The handle is not in my favorite shape, wings are big, upper part of the handle is little thin, but I forgot about it after few shots. I recommend rubbers like Pinyi Bluesponge, Battle ll Provintial and Gold or just H3 for forehand, and D09C, Pinyi TsuNami or FastArc G1 for backhand.
