I always pick out a few choice games for a wish list that I send to soera and I also mention that they can use my site wish list too. It doesn't matter to me, and I think it helps to give people flexibility or simplicity depending on what you're working with.
I've had a mix over the past three years. My first SS didn't choose anything from my hand-picked wish list. My second SS only did one game from my hand-picked wish list and the rest from my site one. My SS last year did the opposite, 3/4 games were from my hand-picked wish list and they also threw in some very fun extras
