I went with the 2 because of the dual low handles and the eyelets that allow the sled to be used for pulls as well as pushing.
On another note, you'll have to unload this from the semi yourself so be prepared for that. Not that Prowlers are heavy, but my experience was the UPS driver was trying to do everything he could to avoid actually delivering it to my home and having to drive down a residential street. Also, the shipping cost is very high because the Prowler is shipped on a pallet that UPS claims takes the shipping weight from 80 pounds to 145 pounds. The actual shipping has been the only low point for me.
