Pre-workouts similar to Mr. Hyde?

I have tried several pre-workouts (C4, Gold Standard by Optimum Nutrition, Fitmiss Ignite) and I don't know if it's because of my caffeine tolerance or what, but the only one that has worked is Mr. Hyde by Pro Supps. I do have a sample of BSN NO-Xplode that I'm optimistic about, but I'm not sure about it yet.

For what it's worth, I'm a female, 5'11" right at 200lbs. I don't use pre-workout every time I go to the gym, but I would like to have more than one that works for me so I can alternate them.

My boyfriend has suggested Predator by Beast Sports Nutrition. Thoughts?
