I've been up there twice now, once in 2006 and in 2007.

In Tuckerman I've been down:
I've been down:
1 - Left Gulley
3 - The Chute
8 - The Lip
9 - The Sluice
10 - Right Gully
My favorite is the Chute, I think it's the steepest and also has one of the longest pitches.
And At Hillmans I've been down,
3 - Hillmans Highway
7 - Lower Snowfield
Dodge's is number 4 in this picture. It's supposed to be the most difficult line at Tux, and sometimes needs to be descended (aided) depending on how an icefall fills in with snow. However I think that guy is a big chump for snowboarding with an iceaxe in his hand. There are far safer ways to self arrest. It hasn't been safe to ride it both times I've been up there. Hopefully this year!
For the most part, you don't need ice climbing gear in tux, unless you're doing a winter assent. To put it best, I always say, if you need crampons and an ice axe to climb up it, do you really want to be skiing/boarding down it.
Another pictures of Dodge's Drop, just to the right of my friend's ski tip.
Anyway, sorry to hijack your silverton thread!
