I am like you, I use solvenless wax pretty much exclusively now. I got away from the bho despite how good this shit is around here, lol.
Atmos is actually recommended by some for ice wax. But yea, that hot coil is gonna get residue on it no matter how good your shit is. And with ice wax and even bho, the issue is the direct heat is too much and ruins the flavor. A Vape Scrape(silicone tipped stainless tool) and some 91% iso will keep it in good shape tho.
There are a few other pens out there with better designs. I have not looked into it in a long time. I may do some looking today as I too am in the market for different ways to use SLW. The Cera is a good place to start. Or perhaps one with a better replaceable coil piece, Ti2 coil and ceramic wick is getting popular. I've even seen them with lil screens over the coil now, seems like that would produce something like a screen melt, video for your pleasure on that below, hehe.
PS> My go-to for SLW recently is Ti2 screen over a bowl or slide, then lightly hit it with the flame from some hempwick while you hit the pipe. Gives good hits and flavor if you do it right. That or I just roll it up with some flower, spliff style.
