First, the drilling will have a small influence on the ball motion. The cover and core have more influence than drilling. What are you looking for in motion? More arc motion for up and in type shots (likely with your lower speed and revs)? Or a shorter more abrupt reaction at the end? The Burn is a higher RG core, so should go longer / rev a little later anyway (even though MOTIV has it in the middle spot on the low/mid oil row). Of your 2 options listed, The first one with the 65 degree VAL angle (lower pin) should arc more. The second one with the 45 degree VAL angle (possibly pin next to the ring finger or in it) would save a little more reaction for the end. However, the difference between the 2 layouts may not be enough to really notice - especially with lower revs.
My opinion is to go with a layout that has proven effective for you in the past. Check with your driller for further advice.
