I have the kuryakyn stirrups and wide footpegs. The are very comfortable without the look of floorboards, which I don't like. The only thing you need to know is that the stirrups will spin, ie. not stay in place no matter how tight you assemble them. I cut grooves and roughed up the meeting surfaces with dremel carbide tips. I then put a bunch of J-B Weld into the female part and tightened it up. You can remove the J-B weld that squeezed out (while it is still wet) with paper towel. I put loc-tite on the 1/4" bolt that holds it all together. I can now stand or jump on the stirrups and they don't budge. Last thing you want is them spinning when you put pressure on them crossing an obstacle.
