I think this is a safe comparison:
In today's oil environment, the Heat and the Soln PPEx both handle their intended oil target, medium-light very well. However, they do it in a slightly different manner. The Heat is slightly earlier with slightly less backend, IN GENERAL (same drilling, same bowler, same oil pattern, and all that "rot"). That ball path being the case, I, who usually have some degree of control problem with extra flippy balls, do not (yet) find the Soln PPEx to be uncontrollable.
