I've not used a Solo, but been a user of Arizer Airs (both 1+2) for few years now. I think they all work in similar ways, so accessories should fit all their models. I upgraded mine to all glass mouth pieces as this improved flavour and made the hit much smoother (you can find them in black glass on vape fiend, which also adds to the stealth).
For flower, I tend to start on 195c, and then finish off with a few draws at 200c (usually on a 2nd cycle). The first few hits are always the fullest (flavour and clouds) but the rest also work well, and the temperature difference seems to create different effects. I probably get around 10 - 15 hits per cycle. Some strains vape smoother than others.
Agree with the advice below about packing the stems - do so fairly loosely at about 3/4 - 4/5 full.
Also, the shift from smoking to vaping can take a while to adapt too. At first, it can feel like something is missing, but after a few days or so(without combusting anything) it suddenly feels *much* better than smoking ever could...so stick with it
