I run straight braid and have for 15+ years, salmon, steelhead, sturgeon, hali, tuna..... on long range trips they used to not like braid at all then top shots for tangles and such of 150', then they started running 100' top shot, then they went to 50' top shots.
Last trip most guys use about 20-25' top shot at the most. The live bait can tow the braided line much easier than the heavier mono. Last trip many times we were using straight braid with a flourocarbon leader to our hook. I think mostly in the beginning they were not used to the braided line, and they have slowly gotten used to it and it is a norm now.
It is very true that mono is easier to untangle, but if I get a bad tangle I cut it off regardless of if it is mono or braid...... at least it is easier to add braid to braid with a very small connection. Braid will definitely cut you and is not needed for the fish we catch, but I don't want to switch back and forth, so I fill it up with braid and go fishing.....
Like most things it is personal preference..... braid has no stretch, and works the drag harder on your reels, mono will stretch and not be so hard on you gear on a take down, the drag wont work as hard because the line is stretching and helping wear down the fish. Braid it is direct connect....
