I had mine out today for a short while, but it was a little chilly.
The 3.54 with the Tremec, I think, is absolutely perfect -- it might not be perfect for the drag strip, but it allows you to go slowly in first gear, which is nice. Now it can be a tricky call for the fifth gear, but I went with the .64 -- around here highway speeds are 70 and above and my engine is comfortable at just over 2000RPM. One of my absolute favorite things to do is to take her out on the interstates towards the mountains and just piddle along at 70mph at just a hair over 2000RPM. There's more wind noise than there is side pipe noise, and it's just delightful. It's a cruise-only gear, though. Certainly not for road racing.
