Is Berkley crystal fishing line any good for breamflathead fishing?

In all reality, fireline isn't really good for anything. There are better braided lines to use if braid is your preference. If you do choose to use braid, check out Power Pro. It offers a lot of different sizes, and line tests.

If I were chasing bream and flathead, I would use a fluorocarbon line since it practically disappears underwater.

I hope this helps you. Feel free to stop by <a class="url" target="_blank" rel="nofollow noreferrer" href="/to/?target=http://www.ultralight-fishing.com">My Ultralight Fishing Blog</a> to get more tips and techniques for bream and flatheads!
