So I took the plunge and ordered up a new wheel.
Powertap 2.4 SL, 32 spoke, cx-ray spokes, velocity aerohead OC rim (in full on Manchester United red!) Pimpin'.
I know I said I was gonna go for the Pro - but I normally ride most of the time on the trainer with the front of the bike completely covered by a really big towel - so the wireless functionality adds a whole bunch of convenience.
After pretty much being off the bike, apart from a couple of weeks in July, for the last 4 months this should be interesting - moreso because of the lung function issues I've been having. I recently had a lung function test and will have another in December so it'd be interesting to have lung function numbers to go with the actual power numbers.
