I recently got a convoy S6, went with the T6-4C 2800mA driver , love it.
It is more throwy than i expected.
It does get hot fast on high but that’s fine if you just keep that mode for turbo or use it until you can’t hold it any longer 
- it’s always good to have it if you need it there.
I put a forward clicky in mine. Great light for $20 or so.
