I have spools of both in the 30# class and only PP in 50#. I've been a PP user for a few years and just started on the Sufix last year. Maybe I've been lucky but I've never ended up with one of those 'bad spools' of PP yet. The Sufix has a higher thread count so theoretically it may perform better. However in my experience I can't really find any difference so I'll keep on buying the PP as it's a little cheaper.
I used to use 20#pp on my light stuff to many breakoffs I switched to 30# pp and have had few problems.I was going to put 50# pp on my 10 foot rod for my heavy tackle but when I here these comments I dont no if it is worth loosing a 20$ plug.I tried different tipes of mono and hate it.
I'm thinking now of trying suffix how is the casting and price on it compared to pp?
I havent had any bad PP either, it always works well. Last year played with the big game braid and it worked well. Got a few mystery breaks one night at the canal, probably took a bit of abuse and i didnt notice it.
