I've got an Exped 5R in a long/wide size. It's listed as 77.6" x 25.6" x 3". I had a 7R a couple of years ago in the same size. It was a 3.5" thick mattress though. Honestly they've been some of the comfiest sleeping pads I've owned.
I'm pretty much the same size as you are as well. I'm 6'2" and 215. I've never found the size of the pad to be too short or narrow. And I toss and turn like I'm clothes in a dryer.
There's plenty of thickness to keep you from sinking in even if you're a side sleeper. The only downside to the pad is it's packed size. Which is bulkier than the traditional suggested sleeping pads, but it's really not that bad for what you get.
Also I just looked at the Megamat. The 5R has a higher r-value, is still 3" vs 4", but that megamat packed size isn't worth the extra space at all in my opinion. I think the bulk of the megamat will cause more problems than it solves in the long run.
Yeah 8 is pretty crazy, I have an exped 7R and sleep with it literally on top of snow with no problems. Slept in -20°C a few weeks ago and the pad was fine but my bag wasn’t warm enough
I have the 3R MW and 5R MW. I’m going on a bikepacking trip next week with temps around 5-10 at night. I will bring my 3R. If I have the room for it on the bike I might go for the 5R. I will make the final decision as I pack my bike.
I did buy a 7R to replace my xtherm, but the down seemed poorly distributed when I held it up to the light so I returned it.
5R with a ccf on top served me well at -5-10C last winter.
I had a thermarest x-lite, an uberlite, a sea to summit, and then I got an Exped. I love my Exped. I love the wide version. I had no idea how much better a rectangle is. I bought a 7R for winter and a 3R for the other seasons and I will sing its praises all day.
