I recently purchased the stiga vps infinity and glues the stiga calibra tour m and tour s to it.
I find that the blade is well suited to an aggressive, close to the table game, with great feeling. The blades large sweet spot also suits the short game, but you really have loosen your grip.
Loops and smashes really are a breeze with this blade, i can loop and smash from close / mid distance with accurate placement, particularly with more challenging strokes like sidespin loops.
I agree with others who say that away from the table, this blade really requires careful attention and great technique, as it lacks gears. I often found that the ball would either dip into the net or fly way off the end of the table when performing away from the table loops and counter loops. However, this could be down to the rubbers.
Its an awesome blade though and suits the calibra tour rubbers well.
P.s. the sound is amazingly crisp and feels very satisfying to hit with!
