has anyone compared these side by side? it seems to me like the only big difference between the two are the cable slide vs. cable roller. kind of like the Attack and Carnage, basically the same bow with different cable guards. are the draws, back wall, hand shock, speed, etc. similiar between the Method and Motives??? i know the speed on the Motives will be a tad higher due to the cable roller loading up the limbs slightly sooner but is everything else virtually the same? is there that much more of a difference to justify the extra $200.00 for the Motives over the Method???
