I rarely lose spinerbaits or buzzbaits to pike…those must have been either very large or had very poor aim.
I never use leaders when fishing specifically for bass but if it’s an issue for you, try a fine wire leader, it shouldn’t affect your buzzbait except for the additional weeds you’ll collect and if the water isn’t too clear, it shouldn’t hurt your spinnerbaits all that much.
I contend that braid cuts just as easy as mono in a pike’s mouth but you may have faster reaction or the stiffer line may get the lure further out of their mouth on the hookset.
Some guys like TyGer leader http://www.tygerleader.com/ for pike while bass fishing too but I haven’t tried it…
