If you make the recipe I posted, try leaving out the Blue Raspberry Cotton Candy. You might really like it but to me, it starts to overpower the other flavors after vaping a tank or two. Koolada could easily be subbed for the WS-23. I wouldn't leave it out but you might find that at .5% it is just refreshing without being super icy. Koolada at .5% will be much more subtle than WS-23 at 1%.
