I'm one of the few, seemingly, people that like the drop solo (at least more than the recurve).
But there's a couple tips to know:
1) The smaller PMMA cap will reduce the chamber and give a lot better flavour. It's more similar to the high end single coil RSAs you can buy. But if you build your coil too high, it will melt the inside of the top cap and that's not a good thing.
2) I use the regular metal cap, but in both cases you get better flavour (and avoid melting the plastic cap) if you build your coil upside down...
