I'm a rather small guy at 5'8" and 160 so anything larger than a 50 ring is a bit much unless it's box pressed. Though I'm happy with a 50 ring I prefer something in the 40's.

SWMBO doesn't care so much for me smoking and I generally don't have too muh more than an hour so 5.5" is generally as long as I go. However on the days I water the grass I am outside for quite some time and if I have to be out in the Texas heat I want to make it worth my sufferage and usually go for a Lonsdale or Churchill.

I've been a bit enamored with the shorties around 4" and mid 30 ring to low 40 ring. Plenty of times I have just 30 mins of smoking time.
