The way I see it you're probably going to try Halo eventually anyway. Might as well do it now while it's on your mind.
Personally, I've had great luck with Halo juices. Of my top 5 current favorites, 4 of them are from Halo. I could have saved a lot of money and a lot of trial and error if I would have started with Halo. But it was fun getting there.
My favorite Halo flavors are:
Tribeca
Southern Classic
Torque56
Malibu
I like Belgian Cocoa and Longhorn too but I can't call them my favorites. I didn't care for Voodoo, Turkish, or Midnight Apple. Prime15 is just OK.
Give them a try. You might find something you really like. Or not but at least you'll know.
