We did An Teallach as our Munro completion - was a great choice, preceded by a scramble along the pinnacles.
Second round was a Ben More Mull finish for me, I think because there was a tradition of so many folk finishing there.
Third round (hopefully next year) will co-incide with finishing my second round of Munro Tops, so is likely to either be An Teallach again (where I finished my first round of Tops) or perhaps Bidean nam Bian. Apart from the first round, where Scoob & Fi were with us, we haven't had any company along, so didn't have to consider which hill from that perspective.
Corbetts - first time was Fraochaidh for no particular reason. I would have preferred to finish on the Beinn Deargs in Fisherfield, but I was looking at a December finish and that was a bit challenging
I have 48 left on the second round and once again it's going to be a December finish (hopefully) so I need to leave one that's manageable in the short cold days. Beinn an Oir on Jura would be nice, but I don't think too practicable for December.
