I'd go with a Hipshot "A" bridge. May cost a bit more but I find they're worth it. The bridge saddle inserts are round so they're "kind to strings" and offer limited spacing adjustment. They also lock into place via locking hex screws. The bridges themselves are available in a number of different spacing options.
