Tubbs Snowhoe Replacement Bindings?

Please pardon the off-season question.

I am looking for a new pair of bindings for my Tubbs snowshoes. The shoes are the Mountain model with viper style crampons. the shoes had originally come with the bear hug binding which did not work well for me. Tubbs swappd out those bindings for a pair of their basic strap bindings. These are an improvement in comfort but won't stay tight. I am looking to upgrade to a better binding.

I miss the old bindings on my Atlas shoes.
