I’ve no particular experience with Sunrace lately but unlike Advent which requires its own shifters it looks like that Sunrace range plays nicely with standard Shimano shift ratios, so grip shifts should work on it? Microshift produce a lot of different shifters for Advent, but grip shifts aren’t one of them. Maybe have a look for some kids MTB reviews and see what they say?
Thanks for your insights. These have been useful to me. I'm now leaning toward the Sunrace M9 derailleur. I'll post some pics if and when I get it installed on my bike then let you know my own thoughts about it.
Cheers!
