although I've used HASL for this pitch package, the better flatness of the ENIG or immersion silver would be more reliable in volume production.
I've found that most fab shops don't charge extra for the silver finish, and it's fine if you handle it correctly and don't want to store the unloaded boards for a long time.

I'd go for ENIG or Immersion Silver.
