No, certainly not suuggesting that-only asking. As you or others have said, there are many roads to the same end destination. I would add, that having the best driver is likely more important.
The prodisc was an improvement over then existing technology- it would be impractical for one of its inventors to not have it as his weapon of choice. If he walked away from it, wouldnt all docs? The m6, now seems to be an improvement over prodisc's perceived short comings. It all comes down to how long each of us can wait for the next best thing or newly discovered drawbacks to existing devices. A bit like when to buy a new laptop! As critical as disc decision is,at some point, we have to pull the trigger.
