I'll add my experience...
I started off doing the rear brakes first as there was a delay on sorting my front bearing adapters. Using the bug m/c, that was the best combination by far so I should have just drilled the front discs to Porsche pattern.
The bug m/c has not got enough displacement for the single pot front calipers no matter how much bleeding you do.
I tried the 924 which I think is 22mm both circuits, that was too hard and no improvement in bias. I settled on the aluminium 944 m/c which still wasn't perfect but the best of the three options (23/19 I think). Ideally a twin m/c with bias bar would have got the best result.
