Hey Tryggve, thanks for reaching out!
First of all, Norwegian Black Metal? How can I start listening to this? I like your style, I think new gear may cause a singularity to appear.
The Alien RS is a fantastic boot, but so is the Travers Carbon. I'd say if you're looking for a new boot in this sub-1000g range you'd be wise to start with the Alien RS based purely on fit, however Scarpa has announced that they officially only want to see the Alien RS skied on anything up to 85mm underfoot, so based on that guideline you'd likely have better success with the Travers Carbon. That being said 85mm underfoot is well within the Alien RS's limits and it's capable of driving a much, much larger ski than that. The Travers Carbon is an interesting boot that behaves fairly similarly to the Alien RS and with a bit of work you'd likely be able to get the width and volume to work for you.
