The PCBs are due to be delivered either tomorrow or Wednesday, so I'll post some photos then.

I had a hard time trying to work out which MOSFET was the best for my particular requirements. I found myself switching between endless datasheets trying to determine the meaningful differences. In the end I decided to put together a spreadsheet, and I've attached a PDF export of the comparison sheet. There's a heat map on each of the attributes, and they are organised into groups according to the voltage class. It's a lot easier to quickly glance and compare now.

The spreadsheet only lists TO-247-4 footprint MOSFETs since that's what my driver board uses, but most models have TO-247-3 equivalents and the attributes should be broadly the same.
