Pickatinny or other mount for red-dot? Single-six

Soon to take delivery of my convertible 9.5" Single-Six and thinking a Burris Fast Fire red dot sight could be fun. I'm not seeing a ton of options for mount plates drilled for the Single-Six, so wondering if anyone has used:

Weigand "mini" Pickatinny mount, or...

EGW sight mount specific to Burris (lower profile than Pickatinny)

... or anything else for the Single-Six?
