i like atama gold because it is right in the middle(weight) of HCK and Koral. and right now it is mild end of winter over here in japan. it is also soft even if hang dried. the fit is perfect. A2 -5'10" 175lbs. it is comfortable and it has a flat collar. alot of people like thick hard to manipulat gis, i am the opposite i like to train with people being able to control me an easily choke me. so when i do put on my HCK or Keiko for competition i feel unchokable!!!
I also like the traditional simple look of a 2 piece kimono.
alot of people complain of seam on back but i never noticed, if one does it is because you are flat on your back(rarely you should ever be flat on your back)
