I tried that trick after the first time you posted it. Works great, and you'd never know it's there.HERE'S ANOTHER TIP:
The case closes with a thin piece of velcro. If you want a tighter fit so your SP doesn't sag inside the case at all, just take a couple pieces of double-sided tape and put them to either side of the velcro. It adds just that little bit extra grip you need.
Are some of these solutions a little ghetto? Sure but that's half the fun. Ghetto is fine so long as it doesn't look ghetto .
