Hints for making a custom wheel template

Suppose you hate the current Wheel template with a passion—and every other template Wheel has used, for that matter. You're in the Wheel rotation or are lucky enough to get the Wild Card spot for GO! and want to create your Wheel template from scratch. What are your suggestions?

Here are mine:

• Have a good variety of values. They're allowed to repeat—in fact, I can't think of a layout, even from the Australian Wheel of Fortune which threw the "multiples of $50" rule out the window, in which they don't. But too few values make the wheel uninteresting. I think ten is enough, but I wouldn't make this a hard rule (I'll live with nine, maybe eight if there's enough spice on the wheel).
  
• Have more low values than high values.
  
• If you do not change the top dollar, do not make a large gap between that and the second-highest value on the wheel. That's one of my gripes with the current releases of the board games—I know it's called Wheel of FORTUNE, but the winner should not be essentially determined by whoever can spin up $5,000 the most often.
  
• Having "danger" zones is fine—I like sticking high dollar values around there—but don't make the wheel too unforgiving. The odds of hitting a penalty space at the start of the current game are 11 in 72 already.
  
• Don't overdo special spaces. This is not Wheel of Cardboard. Individually, none of the non-dollar wedges that get put on the wheel right now are bad ideas, but too many cooks spoil the broth.
  
• Speaking of cardboard, I don't like sticking it on high-valued dollar wedges.
