I like the fly guys who stand in the middle of the run tossing shot and egg sucking leeches under strike indicators. If that's not purist fly fishing, I dunno what is :)
^--- Now THAT looks like a lot of fun!!
Only cool thing I've done with whitefish is catch them on a dry fly (Which I guess is pretty awesome considering they usually live in the deep stuff)
If you are going for work make sure you get something from your HR department at work. They'll be able to whip something up for you that will cause zero hassles at the border.
The Pack comes with everything to hook up your graph up, except the transducer and transducer wire. (All wires to the battery, mount, charger, etc etc)
Frank, I have the Nanok which is a bit cramped for two big dudes, but they do make a bigger model (I forget the name).. You can't beat it for the portability and ease of setup. I also got the insulated model, you don't even need a heater!
The portable ice pack doesn't come with a transducer.. Only the pack itself, the battery and the charger.
Transducer you'll need depending on your unit.

I have both of these and ran my 747c last year out on Simcoe, this year I'll be running the same pack/transducer with my 788ci.
I'd put some washers on the bottom nuts, that's where you'll have your issues. Also it's not like you'll be swinging the thing around from the top, lol. I'm sure it will be fine.
