I want to fish a tube on a jig head.  What works best to keep the tube against the head and not slide down the hook and bend?  I could glue it.  Thoughts...ideas...  Thanks.

Is rigging them with the jighead inside the tube not an option? If not, you might push part of a plastic worm or grub inside the tube so you can push the keeper into that so it has something more solid to hold onto. 

I'm using a jig with a lower spinner blade so I can not put the head inside.  I like the worm in the tube idea.  Thank you.

I have fished tubes for smallmouth before. I fish a brand called Snapback! They are super durable and most importantly, the float. I paired the tube on a wrecking ball jig so it can move around and always be in a feeding position.

A lot of tubes on the market today have solid noses and the keeper on your jig head should hold fairly well, if not a drop of super glue should help. 

I'm in no way attempting to discourage your experimenting with your baits, but the action of an internally weighted tube on the fall is what separates them from other soft plastics. Not to say other rigs don't catch fish, it's a plastic bait with endless possibilities for rigging. As an example, the jig you mentioned can be inserted into the tube on a downward angle and reinserted into the body to give a weedless presentation that will also give the spinner more action.

BTW, Welcome.
