Definitely try Malibu, that was one of my favorites from Halo.
I think their juices are top quality, some of the best I've tried. Clean and consistent, and their presentation is great. I've tried most of the besides all the newer ones. Tribeca is a safe bet and it's ry4ish, Bella Valente is a very strong cigar like vape - not for the weak hearted. Their menthols are great. Torque was my adv for a while, until my tastebuds changed and I really didn't like it anymore. Mailbu is definitley near the top of the list - others really liked this juice as well. Throat hit is powerful and the flavors are incredible.
Their sample pack is a good bet. All in all I think halo is top notch when it comes to juices, highly recommend them.
They have a sub-forum here in the suppliers section, lots of reviews there and also in the juice reviews section.
Good luck on your juice hunt
