This is pretty much where I'm at. I own a smattering of figures from the last several years, bought because of whether I liked the individual designs.

Eh, yeah he's pretty bad too, but at least the parts fold into a shape that's reminiscent of the boxy underside of an XB-70.

It might possibly be the worst Transformer ever. I can't think of another one that so completely fails to hide the robot bits. I mean... it doesn't even hide them a little bit. They're just sitting under the jet.
Thanks for the link. Did this and it worked nicely.
And thanks for the pic. Already enjoying Superion more.
I just pre-ordered the upgrade kit from BBTS. Can't wait.
