Brett,
I also am very fond of WM's Mach I & II.
I agree, their wings leave a bit to be desired.
You difinitaly need to add something to her.
All of that silver will be hard to see, especially with clouds for a background.
My 4* was the same color top and bottom so I put large diamonds on the bottom.
I recommend a racing motif. I'm an old hippie so don't get into the warbirds.
I even look for the ones I like - T34, T28 & AT6, with civilian markings.
Please keep us posted on the outcome.
Good Luck,
