Im thinking im going to go with Look type pedals, I think bigger contact area, really stiff sole will prevent any kind of flexing which seems to be the thing that really hurts, its not so much pressure as flexing the toe thay hurts and my SPD shoes are not as stiff as a road style shoe. Sugery is the last thing I want. 2 total knee replacements and 2 hernia surgeries in the last 5 years is enough for a while.
