It's not a problem over there. Maggots are the #1 bait, by far. (They sell three different types and in multiple colors.) It's just that casters are preferred for certain situations.
Yup! Best fishing videos on YouTube are our brethren overseas using maggots. A lot of my fishing is inspired by them. Those waters have been over fished since the middle ages. They've developed far more exacting methods than ours.
