Hell, you do have a ballin STR team too.
SS4 Goku lead
Pikkon ---- prioritize his super. It'll be very important in the last phase.
Super Gogeta - Pair with Pikkon for PfB link
SS3 GT Goku -- Pair with SS4 Goku
SS Goten (Kid) - Orb Changer
SS3 Vegeta - tank, stunner
SS4 Goku Friend
Make it so your turns are: SS4 Goku/SS3 GT Goku, Pikkon/Super Gogeta. The rest are all fine as 3rd slot filler.
I couldn't imagine having any issues with that at all. What was the team you were using before?
Turles is overkill with both Rose and Black on the team.
He stuns 50% of the time and he will super every time. Their INT teams are "in it for the long haul" teams so that's very useful.
