Agreed. The Blazers may be shorter but they are higher profile. No way do you have less contact. Shooting through a WB you get full contact. Good or bad is for you to decide. Being stiffer they will be more durable than most regular vanes, though, and not wrinkle as badly.

That being said, I shoot neither a WB or vanes (most of the time). I kinda like feathers, too, but that's my personal choice. I do have a couple arrows with vanes, but they are Duravane LP 400's for passing between my cables and a shoot around rest. I have a WB so I might give it a try. I have to switch my bow around from a 3D setup to hunting mode anyway. That ought to take about 3 hours to complete.
