If U r drag racing yeah dual r going to be better..
But, if U r into Trails,MX,XC and screwing around than 2-in-1 is the way to go..
And yes my builder sold me on it....
But, when I start boosting my HP up even more than I will eventually go to a dual setup...but,
for now I will stick w/my 2n1..
just my 2cents
