I've not used Pulse packs, but have several Sky 6S3000 40C that I like using in the 6HV. Terrific packs for the $$ in my experience thus far as well. They tend to be dimensioned a bit differently than many others for some reason, and their published weight specs at HobbyPartz.com are suspect, but, in the end, they've been superb value. I think I paid $40/each for mine, and one set has about 100 flights and have hit the turf at warp speed. Small dent in the front corners...no apparent affects so far. They fly like new, no puffing to date. Bought them in 2011. Bought another set last season too.
