When trying to choose the type of highway peg you want, it's all going to depend on where you want your feet. Kurys or any static peg must be positioned higher than the horizontal engine guard or they will drag in the corners and could upend your bike if you are forced to lean over far enough. As long as you want your feet positioned that high, you'll be fine, plus you can get them installed at the dealer.
There are a couple of board members who have ground some of the teeth off of the Kury 4056 peg mounts that allow them to position them low and raise them up with toes before entering twisties. That's too much work for someone as lazy as I am. Read about it here:

There is a "DIY" peg you can make that will be slightly lower than Kurys but still at the horizontal bar height. You can find it here:

If you want your feet to be positioned lower, ****-O-Pegs is the easiest way to accomplish this. They are spring loaded and when you take your feet off of them for the twisties, they spring up and are safely out of the way. There are 13 or so models from which to choose depending on your inseam and desired foot position. Dealers do not carry these. Check them out here:

Having worked with riders fitting them to pegs, I have to say what works for one may not work for another. Not only are things dependent on your inseam, but also on your weight and its placement. A large butt will put one further forward in the seat making it necessary to spread your knees further apart to get around the fairing. Thick legs can cause the same problems. Also, being bow-legged or having knocked-knees will make a difference.
The only sure way to know if a peg works for you is to try it out. If you can't try a set out on someone's 1800, find out what the company's return policy is before purchasing.
If you decide on MOPs, I'll be glad to help you choose the correct model. Let me know.
