I have tried those as well and liked them except for the weedguard. After a fish or two, it's all bent to heck and a bit of a challenge to get straightened again. I prefer the mono guards.
Found these recently and although I haven't had a chance to throw them yet, I like the small head, guard, and choice of hook sizes, #2, #1, and especially the 1/0. I'll be giving them a workout in 6 weeks or so, Lord willing. 😉 They're a little pricey, probably due to the use of tungsten for the head.
