I use PP 30 on spin reels 50 on conv. I too have had a few mystery breakoffs but not this year. (so far) Although I saw one when a tackle dealer was showing a knot tying braid to mono...50# mono to 50# PP...the knot held, the PP snapped during a hand pull test...everyone was surprised.
It is (usually) very strong and cast excellent but not on all reels. Some are better the others. the 30# cast like 8# test mono.
The feel is unmatched for bottom fishing. It has its problems but IMO the benifits far outweigh the drawbacks so I use it
IMO the SW stealth is just too thick. It is stiff too and I think that is why is casts poorly. Some guys like it.
There is a lot of personal preference in this and IMO you need to load it on a spool or 2 and try it out. (Have the shop load it for you )
Give it a shot....(if you put it on a spin reel...tape your finger befor casting a 3 oz plug into a headwind
)
