You will be fine with either IMO. A fish inhaling your bait 20′ down the flex in the rod will mean little when it has to move a 3/4-1.5 oz bouncer as well. For me thats when line really comes into play, and having some stretch in the leader section will help that, depending on presentation.
In Canada last year we werent setup for bouncing much of anything, and found a nice current spot where the flow dumped out into the main lake and the big girls were stacked on the drop 16-20′ down. All I had was 66m casting rod setup with braid, and my dad had ,his 7′ heavy pike rod. Current was strong so on top of our 1.5 bouncers we added 3/4 rubber core to it as well to get our jointed raps down. Between the both of us we had to get 20fish between 24-30″ those couple days and I cant remember losing any fish BC of a bad rod setup. But, my dad lost all of our bouncers to rocks, and had quite a few fish hit the bait but never hookup. My guess would be I was running braid on my rig, and he had on big mono. Braid allowed me to get vertical more easy, have a better feel for bottom, and I ran a longer leader in than he did to counter the visibility of the braid, and it worked since I got easily 2x more fish. So my recommendation go braid, but make leaders longer than normal.
