I used to always say go start box etc etc -- Because I hate pull starts. Now that I have the roto start, that is my prefered method. My Hyper21 has more power than my Force 25. But since they dont have a roto start plate and I dont want to carry the starter box and battery (it gets heavy) I use the Force 25 with roto start instead of the Hyper 21.

Just my 2cents.
