I think you could use any line in your situation. However, I like the versatility of having the main line as braid. You can tie a leader on of either fluorocarbon or mono and switch out depending on how you are fishing. A mono like Berkely XT would be a good leader if you need something low stretch and very strong, abrasion resistant (wood, rocks, etc). A fluorocarbon leader could work well if you need a faster sink rate when you are down around 20 fow and/or when you need ultra-invisibility.
I agree though with your guide… having good sensitivity and solid hook sets is the way to go in my book. Nothing worse than setting the hook with a rubber band!
