i say ha ftw! you don't have to grind, you don't have to stir, you don't have to worry man! its the best all around vape there is - it blows bags, direct hit, and its a vapebong champ! if you have a bong then you will want the ha because its easy to hook directly to your glass, its small and lightweight, and will produce huge clouds without the need for stirring, or whips! not having to use a whip is a huge bonus. first its less expensive in the long run, second, its an instant bong fill - no sucking air waiting until the vapes travel through the whip, therefore, you get a much better vapor to air ratio = more satisfying hits.
