Eric, the fat cat doesn't come with the shoulder straps, which is OK by me cause I would have probably replaced them anyway, $15 buys a real nice set from a good mountaineering shop. For longer walks I stuff mine in a large back pack, add fins and a pump, lunch and a water filter and I'm maxed out... they don't call it fat for nothin'!
... But a lifelong journey.
I choose fly rods the same way I do women, motorcycles, and cowboy boots...
go with what ever feels good, and keep on hand as many as I can afford
