Best Tintable Polycarbonate Stock lens???

I've been getting a lot of folks lately wanting light brown gradient lenses, usually in Drillmount Cartiers. They've been really picky about their tint color. All the lenses i've tried have come out either off-color or with sharp lines even after a quick dip in the dye or the neutralizer.

Anyone found anything that worked well color-wise?
