Thank you for your response. I'm somewhat of a mover when I sleep, and I'm leaning towards the long version now although it weights 200g more.
If the sleeping bag touches the ground, will it affect the temperature in the sleeping bag? I'm thinking that as I'm using a long sleeping bag (193cm), so ~8cm will reach outside the sleeping pad and touch the floor (although my feet would probably not touch that section, as I'm 185cm tall and the regular sized pad is 183cm). Even if my feet wont touch the colder section, I'm worried that it would lower the temperature in the bag. As mentioned, it goes below freezing point at night where I'm camping.
