2018 R1200GS, 2016 FLHTP
+1I've got a Russell Daylong set...
+1 on the Russell Day Long as I have one on the GS. Easily the best of all of the other seats I've had on this model bike (I'm on my third since 2007). I have tried a similar Bill Mayer saddle, Corbin, & Sargent. The Sargent was the best of those three, but the Day Long eclipses that. I'm 6'1 with a 33" inseam which is helpful with the RDL as the front portion of the seat "wings" do intrude a bit when you put your feet down. But it is something you easily adapt to and does not interfere (helps actually) when standing on the pegs.
Pro-tip: If you ride in cooler climes, get the heated option - expensive but welcome when you need it.
