Hello! I’ve been trying to decide between the Nemo Forte 35 and Disco 30. The first question is being I’m 6’3” and 175 pounds;  should I opt for the Long version or the Regular version of either of these bags? I know for a mummy style bag I need the long version but with the style of these I didn’t know if I should stick with Long or get by with a regular?

Second, is there any real huge difference in these bags besides one is down and the other is synthetic? It looks like the Disco 30 is slightly warmer, lighter and compresses a little better. Is there any different features between the two?
