MK Vantage blades were discontinued a long time ago. Some fitters say that they're on par with the Vision, but YMMV - our archives show some unhappy skaters after a Vantage-to-Vision change. The chart below shows that they're a step up from MK Pro/JW Coronation Ace as freestyle blades; probably the counterpart to Wilson's Four Aces blades.
I've been looking for this chart for a long time...

After looking at some Visions, they're more equivalent to Pattern 99. Theyre basicall to the Pattern 99 what the Gold Star is to the Gold Seal. The pick configuration is almost the same, but the vision has a High-Intermediate Rocker profile. It's very curvy in the front (similar to an MK Pro in that respect) and the Rocker Radius (for gliding) is 7' instead of 8 (MK blade).
The blade probably isn't as strong as the ones (MK/JW blades) that cost more than it, and probably doesn't hold sharpening as well, which is likely why it costs less.
Also, they seem to be harder to get. Frequently skaters have to wait weeks for them and a lot of fitters done stock them. If MK dropped them down to about $325 I reckon they'd sell a ton of them, but that would eat into Phantom and Gold Star sales.
Eclipse Infinity (P99) Pick:
MK Vision Pick:
The Vision is somewhat smaller in the pick and less aggressive (less of an angle on the drag pick, rounder spin rocker), but the general designs of the pick seems aimed to mimic a JW P99.
