Interesting you say that about the pinecil, I'm a little embarrassed to say I haven't touched mine since the day it arrived after impulse buying it. I guess I assumed it wasn't as capable as my Metcal. I'll have to give it an honest try.
Pinecil is a great soldering iron, especially the 88W v2, but it definitely doesn't compare with a fixed temperature inductive Metcal. I haven't found any soldering iron with a PID loop that does, simply because there is zero delay in the Metcal between the time the tip makes contact and the RF reheating it.
