I would be too BD.

No way a 30# braid (of any brand, let alone PP) snaps off on a cast unless it is breaking off at the knot. But this is a well documented issue and although some braids are easier to tie a good knot than others, they all require better and different knot than mono. I have used double uni or palomar and have never experienced a snap off on a cast with any brand of braid regardless of wear. To reduce wear at terminal end though I will use a mono shock tippet for drift fishing. I will also do this when I am changing lures alot too because knots are far less critical and easier to tie with mono than with braid. But with a GOOD knot and straight braid of ANY brand you're NOT going to break or snap off PERIOD. This is also another very good reason to use a mono shock tippet when fishing rivers so that when you do eventually snag up you can intentionally break off at the terminal end without leaving that nasty ol' braid around. But since a mono shock tippet does introduce another knot into the chain I will only use it where appropriate.

Knots, not line strength or consistency, is the big overriding issue with braids.
