I have had an SK 90 and an Evo 100 on my US 60. The SK 90 requires a 15-6 prop so a longer gear or bigger wheels might be needed.
What's wrong with a 14x8 or a 13x10. I've used both and they work very nicely on the SK90.
For $65 or so it's hard to beat the SK for value.
The best price I have found on a SK 90 is ~$100.
