Easy fit drivers for Convoy C8 host?

What are some good drivers for XM-L2/XP-G2 that drop into the Convoy C8 host?

I’ve just bought one of these that I’ve built a direct drive Nichia219 out of. It’s a really nice host so I’d like to make a couple of over driven XP-G2 and L2 ones now. But I’d like an easy drop in driver board that fits these hosts well. I’m not entirely happy with how I’ve rigged up the Nichia.

Thanks.

best 2 that I like which fit.
