Ok, I am trying to decide which go to get. I am going ot put it in a Muggy, I am trying to decide between the .21 or the .25. I want a .21 for fuel economy but I am not sure if they will have enough power to move the muggy well. I currently listed my WS7II on ebay so I have a couple days to decide. From what I got told over and over and over again, the WS7 doesn't have any low end. The muggy has the 8ight T rims and tires on it so they are much smaller then stock. What do you guys suggest. I never tried the ws7 on the muggy, I am waiting on my 1 piece motor mount and some warm weather. What do you guys think?

Thanks in advance,
Craig
