I had a reach on my RK. It put me closer to the bars and lower on the bike. The nose of the seat was narrow so you can get flatfooted pretty easy. My only complaint was that once it was broke in, say 1000 miles or so it seemed to get hard.
My dealer let me try out a reach seat on my 09 Road Glide. It moved me only slightly lower and slightly closer to the bars. I held off on buying it and eventually bought a sundowner. It did the same thing the reach seat did and is supposed to be better for long distance touring. Talk to your dealer about trying out the seats in the parking lot. I think I remember reading that some dealers will actually lend you a seat for a few hours or a day but my dealer wasn't one of them. Good luck in your search.
