Ammermuller showed he was much faster than Vietoris, both in Sepang and in Zhuhai. However, Ammermuller did some stupid actions in Sepang of which he can't be proud of. Then again, in Zhuhai he had a fair fight with Adrian Zaugg, that was very close racing and it didn't end in drama.
After Ammermuller winning in Zhuhai, I didn't expect Vietoris to come back, certainly not this soon... It surprised me.
The best driver strategy is very hard to determine. I think it depends on how Vietoris improved after his 'slow' start this season. If he catches up, it might be a good idea to share the races with Ammermuller. If he doesn't, than it's better to hand the car over to Ammermuller, let him make the best of the season and come back and try again next season...
