Sorry been quite busy. Not real familiar with concentrate terminology...by full melt if your referring to bubble, i have not tried personally, but i would say its safe to say the white rod should be able to handle pretty much any type of concentrate.
The thicker and more solid, the shorter the coil should be. Ive pretty much only had shatter since i got the persei. I had to cut the coil to 30% to get it to work consistantly with the white rod, and have been using the same coil and oil with the black rod so from my experience I would say whatever sized coil you use with the white rod should also work for the black rod. Although if your using a full coil with the white rod i dont think that would work as well with the black rod even with the same oil. I would probably suggest half a coil (50%) as the biggest size with the black rod.
With the shatter i have, it would melt instantly into the coil with the white rod, its a little more difficult to get it to melt in fully with the black rod, and i do have to scrape around the top of the coil/outer diameter against the walls of the chamber from time to time which is the only trade off, but you also dont have to worry about pulsing the button and/or burning oil as well as not having to worry about it leaking period...
Thicker, more solid oil/concentrates i would suggest a 30% coil, with the ceramic rod just slightly sticking out above the coil. For both the black and white rods.
Waxes probably 30-40% coil with the black rod, 40-50% coil with the white rod
And liquidy oils 50% with the black rod, 50%-full coil with the white rod.
Ive only used shatter though, so those are just assumptions.
Also I would say thats a great idea to have one with the black rod and one with the white rod, but not necessary. At least for me...i havent even touched or thought about the white rod since i got the black rod. I did think it would be nice to have an extra upper section (where the rod and coil goes) so you could have one for herbs and one for oil without having to worry about removing the coil everytime. But if your only doing oil its really easy to just switch the rods out, and in that case it might be good to just set the other one aside(minus the extra rod) so you have spare parts in case something happens or you lose something?
Okay so are you recommending the black rod for just herbs now too (like the blue rod was) as well as just oil and/or mixed?
I havent gotten a chance to try my black rod with just herbs yet but should be able to tomorrow so ill report back sometime in the next few days as how it goes
What im saying is the black rods will heat up faster and hotter, if you have a Persei it shouldn't be a issue if you pulse the button.
