From mass to cutting cycle

I'm about to finnish my third cycle (8 weeks of sustanon and deca). I have made very nice muscle and strenght gains, but I have also gained some fat/water mass.

My question is, what would you guys recommend me to do... should I do the PCT and take a break before starting the cutting cycle or would it be okay for me to start it right away?

And If you think its okay to start right away with cutting cycle, what kind of cycle would you recommend?

ever try dieting?

Yes, I sure have... I don't have any problems dieting.. just wanted your opinion about weither it's wise to start new cycle right away or not. I really don't want to lose just gained muscle.
