I'm cancelling my fitting with AG on Sunday after reading through this. I had my doubts last Sunday anyway when i was trying out a 910 D3 with a RIP shaft. I was definitely hitting it further but wanted to try out a few different shafts. The answer from the bloke (who i was assured is one of the best in the area) was that the RIP shaft is the only one that really works with the 910 and there was no need to try different shafts. Honestly.
I told the guy straight to his face that i'd never heard such tosh.
