I run 20lb suffix braid to a 12 lb flouro leader on a 7ft fast action SLX with a 7.3:1 Tatula. With this setup, I felt like I have significantly better hookups with finesse jigs than full size. I also fish a lake with heavy pressure, so I usually opt for finesse jigs anyway.
I'm fishing more in that 3/8 to 1/2oz range, and I'm running 30lb braid to a 12 or 16lb fluoro leader, depending on how quickly the leader is getting chewed up.
I also just picked up a few finesse jigs recently so I'm gonna have to try them as well.
