[m110]

The G50 is more robust and seems to last longer in terms of maintaining shifting bliss. There was a recent thread on how no one posts about rebuilding g50s; partly because they are newer, partly becasause it is not straightforward. When both are newly rebuilt (and the 915 with a few upgrades) I would take either. The G50 is more modern and consistent (even when cold) which is important to me. Porsche changed for a reason.
