I glued my blazers as far out as my bitz permits to go, topnotch is a far to the left and bottum as far to the right as possible, so you can say they're offset.
I noticed the same thing, my vanes hit the black bristles when they went through the WB. I took my arrows and let them drop through the WB which I mounted on the side of a table, I simply turned my nocks untill the arrows fell straight through without getting bumped by the black hairs in the WB.
When you look at the vanes they are parallel to the ends of the black bristles at the startand when the arrow starts turning the black hairs stay nicely inbetween the length of my vanes....
All you need to find out is how your offset spins, to the left or the right.....

But I too am tempted by the new hostage design, I might try one out as well.....
