Similar story to Terry. I used braid for almost all my trotting for three or four years. There are both up and downsides to using it. It can render a rod, that's just fine with mono, to seem almost useless. Get the rod choice wrong and you'll bounce hooks out quite often. I never found any need to use a mono leader with braid, I simply stuck to my normal mono/fluoro hook lengths. However, that undoubtedly made my choice of rod even more critical. Striking and control, even at distance, can be excellent due to how well it floats and how little stretch it has. In benign wind conditions, it's fantastic. However, in less than perfect wind conditions, or uneven, boily water, it's not so much fun.
I've seen people suggest that wind knots are an issue, but I never had that problem. However, though different braids are afflicted to different degrees, the noise through rod rings can be an issue for some. The biggest issue I encountered was actually finding braid in sensible strains. Some brands do braids of around 10lb and less, but getting hold of it can be tricky.
