Rickey I would go with a Saito 120. The only other thing is cost if the 120 and the 150 are very close go with the 150. The plane likes power. I had a freind who built one with a 61 in it. It barely flew. He put a Supertiger 90 in it. It then flew well. I think a 120 or a 150 would do it. If you like the Saito 150 then by all means get one. Rule #1 it's your plane, do what you want. Good luck.
