As you asked, I thought I'd put my 2p worth in, in case you haven't ordered it yet......

A couple of months back I had the opportunity to look at the 4*60 (red) and Tiger 60 side by side in the LHS. The first thing that struck me was how DULL that red oracover is that SIG use on the ARF. The next obvious difference is that Goldberg supply a trike set of legs whereas the 4* is a tail dragger. The Tiger has a hard point in front of the wing for a taildragger gear, and blind nuts pre-installed at the back for the tail wheel. The other main difference no-one really talks about is the plug in wings on the Tiger.
I presume the wings on the 4*60 are one piece and are glued together using a wood dihedral brace. The wings on the Tiger are joined using aluminum tubes, each half has a front dowel and a bolt down at the rear. This means that you can seperate the wings for transportation.
Overall, I thought that the Tiger was a better quality product than the $*, so you can guess which I went for.
The Tiger is slightly more expensive than the 4*, then if you want to fly it as a taildragger there's also the cost of the LG to add. It seems though that many people choose to assemble as a trike, then convert to taildragger later...
