An update: so I saw that the fund choices for my UK pension weren't good, but they weren't horrible, and I don't need the money so I thought I'd switch to an equity fund and let it ride for a couple of decades. Currently it's in a "With-Profits" fund, which means there's no telling what it's in, what bonus they might give or take away, or what it's costing me.
Later I realized that on top of the already exorbitant 0.51% expanse ratio, the equity fund had a 5.25% bid/offer spread. Luckily the fund switch request didn't go through.
I'm back to wanting my money out of there ASAP. I'd rather pay the tax now than pay those blood-suckers now, and pay tax later anyway.
