The fixed torch is what has always kept me from purchasing a Rio, even though all the love it gets around here still has me wanting to try it.
It's just that in my experience torching my bangers, I always get a better experience when I just don't heat the banger from the bottom, but that I alternate between the bottom and the sides (not heating all the way up the sides, but at least halfway up to keep the temperature difference between the thick bottom and the immediate area at the sides to a minimum). Otherwise, the oil wants to run for its life up the sides away from the heat and it can be wasteful/inefficient. That's what has always kept me from pulling the trigger on the Rio so far.
RiO fucking rocks... I just prefer different quartz.
The system works, and so fuckin well, I'd love to hear your thoughts if you try one! It is the ultimate in efficiency and with the right cap, you can spread your material around the dish without sending it up the walls...
I will say this doesn't seem to be an issue with the standard core banger though... Place dab in the center of the core, and that is what is heating up, so I don't know...
I find it to be a FAR nicer experience to load the trough instead of the top/center of the core. It takes a LOT of heat to melt when you load the center of the core. The moment you finally get that chunk of core to a temp that begins to melt, the trough is already overheated and your material is going to run right into the hot spots... It is not nearly as flavorful as loading the trough. You will have much better temp control, you will be able to hit at lower temps and save a little butane. There really is little benefit to loading the core unless you like hot hits.
Give the trough a try and report back!
I have never really been a fan of core bangers, tend to favor round bottoms and standard bangers the most. I went through a deep dish period, but most my caps preform exceptionally better with standard depth dishes. I also tend to always favor standard clear quartz over opaque.
