This spring I'd like to try "mega" tubes for bedded bass. I have a couple questions about these 6+ inch tube baits. First, how do you rig them? Also, what are you're favorite brands, baits, and colors? So far I'm looking at the Gitzit super tube and Mizmo Ish tube. What would you add? Thanks.

there some big ones on tackle wharehouse made by canyon plastic I think is the company 

I normally just use smaller sized tubes on beds. When they're locked on they'll bite anything. when theyre skiddish I go with a smaller bait. Guys in chicago will use crappie jigs when the bite really tough

I used smaller 3.5-4 inch tubes on bedded smallmouth last year with success. Just looking for a bigger bite.

The biggest tubes I've used are 5.25 in.(NetBait BK Tube), but hook sizes and rigging options won't differ much for the tubes you'll be using. For bed fishing, you don't want or need action on the fall so internal weighting would only be considered during the nest building stage.  I would suggest a stand-up style jig head, or a swivel head style either of which will give the tube a tail up attitude when sitting on the bed. 

The other option and one that I use, is a tungsten bullet weight pegged a half inch or so above the line tie of a 5/0 round bend worm hook.  I've found that I get more hook-ups with those vs, EWG or most straight shank hooks as they are longer. The small space between the bullet weight and the nose of the tube gives it freedom of movement.
