I'm with Jake on the i15s-excellent accuracy and the 3i makes going with a fairway wood no problem. That will probably change at Legends' distances but can't say yet.
What I found interesting is the difference in how the Tri driver and the newer R9 mix with them. The R9 is supposed to have the same meter speed as the Tri but it comes across a bit slower because of the way it accelerates through the swing. The Tri has a slower start with a fast finish while the R9 is consistent throughout the swing. This makes it a little trickier matching the i15 swing as there is a tendency to hit the irons late. They have the same type of acceleration that the Tri does-slow start, fast finish.
I have the G10s too but haven't played them for a while. LOL-the meter's too slow but I believe the R9 would match them better than the Tri even though it has a faster meter.
