I've used 4lb Mr Crappie Super hi-vis (made in USA version) and it worked well. The latest version (made in Taiwan) has had some negative press, even here on the site. I can't vouch for that, as I've switched over to 6lb Vicious Panfish hi-vis line. The jury is still out on it, but it does seem to be decent line. I have no complaints on it, yet.
