for the guys to help you with this let them know your setup, what type of device/battery & tank or carto/attomizer each delivery system will have a diff answer.
you could google for ecig/vapor shops in your location. Most, not all, most shops will have a sample section(bar) so you can try their juices, I did this & found a new flavor i didn't think i would like but did
Get a extra drip tip & ask your friends to try a puff from their set up----I do this one alot with my budies.
Sample packs, explore this forum for company suggestions on diff
juice brands....if any peak you intrest go to their sites & read descriptions of their juices, many will offer sample packs from any where to 10$ to 30$ & up....once you find a few flavors you really like you can usually order bigger bottles that will last longer then the saMPLE PACKS..........
Be aware thaat some companies juices will require "steeping" time and that will varry by each company. I always send email prior to order to check on what they suggest for a steeping time of their juices.
hope this helps bro
