For that price just spend a few bucks more and go with the Venom packs. Best packs I've ever run and they are light and very well made. Plus their support is fantastic. You can actually speak to a real live person whenever needed.

I have Track Power and Reedy Saddles and the Venoms I find are a just as good and they maintain their punch throughout. No fading or power drop off until you reach cut-off.
