I bought a $45 TMC bobbin last year and it fits nicely in my hand and is wonderful to work with - this bobbin however will only work without snapping the thread on Big Fly thread. It is a metal tube - I bought a ceramic tube one, and the bobbin itself is too long for my hand; I then spotted a smaller ceramic tubed bobbin that works well and is shorter ( but still a little long for my hand) for only $15.

So, yes my vote is for the ceramic tubes.
