912 engined modern microlights, and reasonably modern PA28s are probably the least problematic in my experience
I have a 912S and have carb ice during warm up 75% of the time I go flying. Once it clears, the a/c is close-cowled enough to keep the carbs toasty warm and it never happens once the temps are up.
Looking forwards to someone saying they are extra careful on frosty mornings....
