I have four IG Prestige MP Pro Stocks and they came with three strips of tape from 10:00 to 2:00 - the swingweight was measured at 384. It's an interesting frame to hit with. The broker had a fairly difficult time selling these - not too many people want frames with that swingweight. You can remove some of it but it seems that most people like to leave them as they received them.
My regular frames are only in the low 360s.
You need an up-close look to be sure on layers. Some folks can do a pretty good job on layering so that it's hard to see multiple layers.
