AICS 2.0 Skins Comparison

[Afkirby]

I have an AICS 2.0 chassis that came with a set of victor company Viperskins. I’m thinking that I might prefer something like an MPA chassis, or a Manner’s T2A or T4A. I usually float my thumb with a traditional stock. How are the oem skins in comparison? I’ve been told the updated thumbhole is superior to the original skins.
