when my buddy did his duals he went with the 23 since he had a higher horsepower motor, when we compared the two side by side i couldn't believe the difference! It's always nice to have the parts already installed even if it is a mild wheeler you never know what you'll do with it later on also you know? i say do it once do it right. i would have spent the extra money if i had seen the difference before i did mine i'll say that at least. But i have also wheeled the crap out of the 21 and been fine. And your wife will get over it man they always do! ha ha
