I use 63/37 solder with a flux core. The Pinecil is amazing, it holds heat really well and gets to 320 C in eight seconds. I didn't calibrate my tip in boiling water, and I don't remember which tip I use now, it's the one that comes by default (B2?).

I only bump it up to 400 C because that was the default, I never use it for more than two or three seconds so the temperature hasn't mattered much. I haven't noticed solder stick, it just sometimes fail to melt properly with large ground planes, so that's when I bump the heat.
