Personally I hate high rep deadlifts. They never worked very well for me. TONS of people make great progress with high rep deadlifts, both lighter (BBB style) and heavier (5 x 5 or starting strength style), but personally, that never worked for my deadlift.
SO, if you've only done the 5 x 10 for one cycle, you might want to just stick with it and keep working, maybe in a few months you will see some SERIOUS gains.
But If you're looking to try something different, I would suggest doing 5 x 10 good mornings. They work a ton of the same muscles and will help your hip, back, and hinge strength. They have a great carry-over to squats too.
Another suggestion is to fool around with speed deadlifts. These, more than anything else, have helped my deadlift. I know they don't really follow the BBB template, so if you are committed to following the program as written than so be it. But again, if you're not loving the 5 x 10, adding some speed pulls in after your heavy stuff might really help.
