I'm going to say that this color change is probably the most unpractical..... Ever. I mean the idea and concept are cool but the angles suck and it only be performed for 1 person at the right angle so basically it's good for the Internet but as far as I'm concerned it's not a real world change. So you end up doing so much work for so little. I'm all up for practising I mean I practice several hours a day but all my effects will work with good if not great angles and are strong. I mean if your gonna learn a change learn shape shifter or ego both have way better angles and if your looking for somthing similar with better angles check out the bertram change.
