Mares Hybrid Pure vs Mares Pure SLS

[alam555]

Hello,
Looking to finally upgrade my old Mares Airtrim(20 yrs!) and am thinking of switching to back inflated. I am also diving a lot more with my kids and want to make sure my buddies are familiar with my equipment in case of emergency. Also have heard lots of good stuff about back inflated for better trim so while I am not ready to switch over BP just yet, I figure this is a good change.

Looking at Mares Hybrid Pure vs Mares Pure SLS. Questions:
Does anyone know what is the difference between the two? I can’t seem to find it anywhere.

Also any comments on either or would be appreciated.
Thanks

Hybrid Pure using MRS weight system.
Pure SLS using SLS weight system.

Hybrid is discontinued.... due to problems with MRS weight system that weights keep falling.
