I have always shot with both the Golden Premiers and the Infinitys on all my bows...even now. I am curious as to your description of the problem. Are you saying that as you draw back the arrow somehow falls between the prongs before you are at full draw? That would and could indicate a few things to me.

One, your release or nockset style is exhibiting a great deal of downward pressure on your arrow during the draw cycle thus forcing it down between the prongs. Two, your prongs are set a bit too wide and, three, your arrow shafts are somehow tapered.

Disregard that last one.

Try adjusting the prongs for a slightly tighter gap. There is no sense in buying a whole new rest when you can simply remedy your problem. Having said that though, the WB is a very popular and effective hunting rest. I set up more of them for customers down at the shop in comparison to any other rest we carry....5 to 1 easily.
