Harness Karabinas

I have a Gin Speedflyer harness and need to get some new Karabinas.

On the Gin Website it showns 2 sizes are available 30mm and 40mm - which Karabinas are originally supplied with the Gin Speedflyer harness for Nano Risers ?

Also is anyone using the Gin Speedflyer harness with different wings - if so did you need to alter the karabinas to suit the different risers ?

Is there a Standard size being used for Speedriding harness/riser connections ?

or
