Here a shelf view of the two but the Med/High is slightly turned back and is not a true representation of the grips profile but i think you get the picture.
The Med/High grip riser has and extra 1/8 th layer of black fiberglass on the front to add additional weight and I believe added to the more pronounced grip profile.
My thoughts on both? My first bow was the standard grip and it feels good but i thought i would like something with a little more meat so on the Triple Carbon I asked Jim to beef it up a little more. Now after shooting both I think I would like a mix between these two. Of course the size of your hand would matter.
Not sure how the grip is compared to hand size but if you were to measure my hand around the thickest part with the hand laying palm side down and measured around the widest point from bottom thumb knuckle all the way around I measure 10”. And then measured from base of palm side to tip of middle finger for length I measure 8”, if that make sense?
