Right just read the manual. It's nothing extreme. Some disassembly but the workings are as I suspected.
The only non-obvious part for QP owners is the NIT removal. It might be totally obvious once you get there. The GT uses dead standard removal tools.
Otherwise I'm happy to let anyone that trusts me be a guinea pig. There is more work than the 4200 however, so I feel a couple of bottles of malt would ample recompense. I'd expect you'd need to hang around for an afternoon to make sure we can take our time. Tea / biscuits / wine / wifi can be provided FOC
