I have worked in research for almost 10 years now. Some of the adademic staff I work with will postulate over theories for an eternity. Others will give it some thought and we will conduct a series of experiments and we will reevalutate from there. Point being, the later gets more meaningful work done.

Test the 1.5:1 rockers and evaluate the results. The reality is it may make little difference to your performance, but you'll learn something along the way.
