i know i want a greedy but the sp and mx model caback wise, i dont know much about and is hoping you guys can help me decide .. and if you know the difference between the two, can you please tell me to help my decision. thanks in advance guys.

WHICH ONE ROCKS?
looking for quite while crusing but can put out power

 

Either one is a good choice

 

the sp looks better IMO but i think the mx is better performance wise. The sp isn't too loud
