I have run T30 Evo GT, T31 GT, T30 Evo, and now T32 GT (in that order) on my FJR1300. The two T30 Evo front tires I used got half the life of any of the others and was not nice the last 25%. And the T30 Evo rear, likewise. The T31 GT front was the best front tire I have used in 85,000 miles. Perfect to the end at about 9500 miles (a record for my front tire).
I don't love the T3x GT on the rear. For some reason I prefer a mushy Michelin PR4GT. And a precise T32 GT on the front.
