They're more a marketing tool than a proper revenue stream, and to eek money out of people that are cash rich and want/need the best of everything, without any analysis outside of the price tag. The profit from the bottom of the range g3 and Kashmir numbers will dwarf it.
It gets people talking about the brand and, dare I say, I think it may be a device to make the rest of their bats look mroe reasonable - the irony is that IMO it cheapens the rest of their range - I thought the (2011) Legends were hand-rolled-on-the-thighs-of-virgins/personally made by the first born of direct blood descendants of Julian Millichamp/Just didn't make Strauss's personal selection/include a key to the GN Factory/AND full use of both Mr Gray and Mr Nicoll's holiday homes in the South of France/from the tree's that we originally planted by Merlin and watered by Lancelot....sort of things, though now it looks as if Sports Direct will be stocking them this year.
In short, I wouldn't be seen dead with one out of principle!
I thought the design of the Legends were pretty much the best bat stickers I have ever seen, though once I got to see the actual sticks I was very disappointed, and by sight/colour/grainage would have made a few of them blemished G2's.
