I'm 5' 10" with a Mustang Classic Touring seat. I went with the 9" recurve, it's awesome, again, measure as per the LRS instructions. Also, it you use a back rest or anything and it props you up a little straighter, then I'd measure with that on too.

Also remember that the stock shield isn't curved on top, the recurve will direct the wind up, so if the stock shield keeps the wind out of your face, you may be able to go a bit shorter so you can look over the shield and it will still keep the wind out of your face.

I always was curious about the flat top, plus got a 2K miles trip coming up with the new GF, she's about as tall as I am, so she'll be sitting up a little higher than the midget I was dating before, so I figured this would be a good time to try out a flat top, especially with the Memorial day sale.
