Should I use a different PT database for each poker site?

[rimmer16]

I'm finally moving on from Pokerstars (500 FPP on .25/.50 takes forever), and I'm not sure what I should do with my Poker Tracker database. I've got just over 10,000 hands, and it already takes a few minutes to export all my player notes - so is there any point in using it for a new poker site, where there's unlikely to be anybody with the same name?

I'm interested in what people who change sites regularly do with their databases, because I can see it turning into this huge bloated mess with only about 10% of the data being useful for exporting to each cardroom. Thanks!
