I'm considering both the S-Works Roll X & Roll X 2Bliss.

I'll be running a DIY SNATS sealant on Bontrager Mustang Disc Tubeless rims with the Bontrager Sealing Strips and valves.

I guess I wonder what the weight difference is between the two. Weightweenies doesn't have a listing and Specialized isn't advertising any on these models.

I there any difference in volume?

Can the 2Bliss be run at lower pressure with a SNATS set up than a "regular" S-Works Roll X?

I've been running '02 or '03 S-Works Roll X with the above set up, except on Mavic X317/X517 rims without much problem. So, if the 2Bliss weighs & costs more then why would I mess with it?
