Tail tube or brain teaser?

I've been having a lot of fun with my new gelding, he's incredibly patient in the barn for a 4 year old and just oh so mellow under saddle. Such a treat to be around. I figured I should maybe go pick a few things up for him so I went on a bit of a shopping trip today. He's now got his very own fancy padded hunter bridle and matching martingale. Looks pretty swanky in it too! Now this horse has THE most amazing tail I think I've ever seen. Touches the ground when he's standing in the stall and is thick as can be. I figured I should maybe put it in a tail bag to keep it nice and see how long I get get it hehe. So I bought one of those "tail tubes" that has the 3 separate sections to put the tail in and then you braid it and "voila!". Well... I think that's easier said that done. Slippery tail + slippery fabric = how in the world does this work?!?! After a good while of fighting with it, I got it in and it looks pretty decent. Lets hope it stays in for awhile so I don't have to re-do it anytime soon! I think this winter might involve quite a bit of trailering out to other barns...with bigger arenas. Our arena is just so darned tiny. I'm grateful to have an arena but this guy is just SO big we seem to make it down the long wall in a few large canter strides. I kinda feel like I'm trying to drive a large yacht round a small duck pond on this guy! The one thing I've got to figure out for him is a new name. He came with the name "Cocoa" and I'm just not sure it suits him. He's a big, fancy boy and needs a name to suit him. His sire is "Beau Soleil" and his dam goes back to Northern Dancer. So far I haven't come up with anything good. Hopefully I will figure it out soon so I can quit calling him "the moose" or "Mr. Brown" or whatever else comes to mind at the moment lol!
