Super-Tuk Substitute?

[Rufus]

Bought a pair of Super-Tuks (sp?) stays that have worked great over the last couple of years but are getting long in the tooth. The company appears to have gone belly up and wanted to get recommendations for stays you may use to keep your shirt tucked while officiating. I've tried sansabelt and the wrap-around belt thing and neither work as well as stays.

Thanks in advance.
