Which ball should i use first for med/heavy oil condition?

According to motiv ball guide:

covert revolt: 14 length/ 18 backend/ 55 total hook/ 5" flare     2.5 rg /.056 diff
gt:      14 length/ 16 backend/ 55 total hook/ 5" flare    2.53 rg/.047 diff   

But in BJI:

covert revot: 49 total hook/ 17 length/ 13 break point shape
gt:     51.5 total hook/ 15 length/ 14 break point shape

I am a little speed dominant player. Both of them has 2000 sanded.


Any input will be greatly appreciated.  Thank you

Which Revolt?

Leftybowler70's response nailed it. 
Covert Revolt better on the fresh, Forza GT better for the transition, especially on medium conditions.
The Forza GT is a great benchmark ball, but performs at it's best when the lanes start to breakdown.  For me usually the middle of the second game. Being so controllable I can stay with it all the way thru the 3rd game on medium conditions.
