Been using my JC's for about a week. very hard padding at first, great hand protection, awesome quality, thick leather, comfortable liner. I have the 16 oz'ers, I think they will make excellent sparring gloves once they break in. Slim hand compartment which is nice, I have long fingers and they just fit into the gloves. I will post a full review with pics later. Very happy with my purchase and Juan was awesome to deal with. Highly recommend them. Personally I prefer them to my Cleto's and Rival's. I have only used grant's twice, so I cant compare directly.
