Nikaya Sutta Recommendations for beginner with experience practicing Vipassana

I have been practicing Vipassana for quite a while (2 and a half years). Now, I want to also dwell into the teachings of Buddha as presented in Suttas and apply those teaching in my everyday life. I have read a bit about the Majjhima Nikaya and the Samyutta Nikaya but I'm in a dilemma and not sure whether or not other Nikayas are suitable for a beginner. With which Sutta (Nikaya) should I start with?
