Some answers
Kempo-
I think you might prefer this jacket to the Meteor. Here are the answers to your questions. Keep in mind, I am still in the "honeymoon" phase with this jacket. It is the perfect jacket right now. There will probably be some nit-picky things that come up as I wear it more often. I haven't tested the "100% waterproof" claim yet, but I wasn't disappointed with my last JR jacket.
1. Sleeve/cuff retention is similar to the Meteor. However, there is a pretty large area of Velcro. Also, there is a small square of Velcro to be used when the cuffs are not tightened around the wrist.
2. The neck area is secured with a large area of Velcro as well, no snaps. The neck in this jacket is the most comfortable I have ever experienced.
3. This jacket also has zippered vents at the level of the bicep and in the back. I don't know of a better system (there probably is one). All the Jackets I've owned with arm vents have used zippers.
4. The liner attaches to the sleeves with Velcro! This is a huge plus in my opinion. My Joe Rocket "Velocity" jacket uses the button and loop system that you mentioned and the loop broke in one of my sleeves as well (an easy fix, but annoying). Also, the liner doesn't twist in the sleeves when it's attached with Velcro.
I've had good experiences with all of my JR products (Ballistic 1.0 Jacket and pants, Phoenix 1.0 jacket and pants, Velocity jacket, Power Trip winter gloves). JR products provide much bang for the buck, and, overall, the fit/finish is very high relative to cost. With production of the "Endurance" jacket JR appears to have raised the bar again.
