New Balance Prism & Propel (1) Rebel 2 replacement ?

Hi,

I wonder how the Rebel 2 compares with the prism and propel. I found the propel (1) tended to bottom out after about a 5km run because of it softness especially when I tried to pick up the pace - it seemed better for slower runs. The prism I found better, more stable and firmer but didn't quite have the bounce of the propel.

Is the Rebel more cushioned (less bottoming out) than them and more responsive. I also tend to be a heel and midfoot striker so would it be stable enough. I am also around 74kg so maybe that could contribute to the bottoming out . Thanks, any input would be helpful. Thanks.

Steve
