Yes...
However, I need to try them both individually to get a feel for how they are.
I'm a hardcore stim junkie, so it should be interesting to see how the UPO stacks up. I've done some PWOs that were more 'mental' and 'focus' oriented, and liked the ones that worked, so it will be a toss up to see what I like better. If they both do as advertised and as well as the reviews say, I'll be in for one hell of a ride stacking them.
If you can bench more than you can squat, you're doing it wrong!
