If you're just grabbing a pair off the shelf and don't put too much emphasis into get Hypercomp and stiffer thrighrise, I'd just go the Senior route.
I put a pair of senior R/GT 1's through the ringer and they held up very well and never had any issues with performance, durability, and protection.
Keep in mind that the difference between a Warrior pad with and without the hypercomp is very noticeable. My thighrise on my R/GT2 Pros are night and day difference compared to my senior set.
