you could use whatever you have...i use a mixer of nice bud and some extra stuff....if you let it sit for long enough, i will be good....what ever you use.
about a .5 to a gram per ounce of 151 will be pretty potent. If your gonna take a shot of it or make a mixed drink....you could add a little honey to make it less harsh....im not really a big drinker, its more for my buddy's, they seem to enjoy it
