Dew Strap Sizing

[groberts]

I need to get dew straps for (1) my WO GT 81 - circumferance 330mm, and (2) a WO 50mm guidescope - circumferance 185mm, and wonder how exact the fit needs to be?

FLO have recommended this Lynx Astro 30cm for the GT81, which of course is 30mm too short, does this matter / is there an alternative elsewhere that will fit better? 

Staying with  Lynx equivalent for the guidescope would be either be 150mm or 200mm - same question, which one or is there a better fit?

I have a Lynx Astro strap for 5" scopes, it works great on my 4.5", 4" and 3" refractors. Best to get the next size up rather than having a tight fit, as you can always overlap them.

The one I got from RVO fastens with Velcro which is on a stretchy bit, so there's quite a bit of play.

I should add I don't use a controller. It runs off my 5v powerbank at about 30%, which is just about right.
