hi, I am on a HH too.
Most any frit will work on a HH, but I would stay away from the reduction frits if you really want the color. just make sure that you use the right CO (96 is the most common for frit and will work in moderation with 104 glass)
You can make your own from any colors you have, just get a big mason jar fill it with ice water, heat a rod of glass and plunge it into the jar. instant frit. This is a great way to use up short pieces too.
Most everything works on a HH. The only think I have had trouble with is RAKU and some of the striking silver glass, and no boro. It can be done, but it takes a lot of effort. everything else is pretty much universal to a coe rather than torch.
Lisi would know better than anyone which is the best color!
