I usually stick to a 50 ring or smaller, sometimes 52....My favorite ring is a 44, 6"-7" Partagas 8-9-8, RyJ Cazadores are some of my current favorites....
It really all depends on my mood and time of day, and how much time I have.....
I think my all time favorite size is a 7 or 7.5 x 42 or 44. But it varies every day!
