I too like Yorkshire tea! Although I try to stick with the Red Rose, and buy its lesser known rival, Lancashire tea!
I haven't come across that one, yet. Do you find there's a lot of difference? I got an English Breakfast tea from Harvey Nics one year, that was good, too. Oh, one place I'd love to shopping for an unlimited amount, is Fortnum and Mason - and I wish BIBA was still open.
