The basket looks very good, also very similiar to the L.L. Bean basket, so my only question is how wide is it? If it's too wide, like the Bean basket, you'll hit your hand when you're executing your downward haul.
When it comes to stripping basket I think it pays to buy one like the Orvis basket. If you're going to build your own and want to buy cones go here:
