I like the concept of the smile handles. I feel they need to be lighter and the length a tad shorter. They are bulky ...perhaps use aluminum and only have one eyelet. The eyelet hits into my other hand and body. When using as an iso handle (vertical) there's a lot if torque on the wrist towards the end of the movement (make handle shorter). Perhaps an add on pad on palm flange for comfort or make it more wide/ contoured.
