I just recently played with my uncle's old PK Copper Ace...it appears to be a 93 sq in midsize. i threw a tournagrip over the original leather to match my preferences..and it still has the cheap nylon original strings.. but when i went out to hit with it, i almost died. the flex was amazing, it is one of the flexiest i've ever played with. the power was nonexistant, which is ok, b/c i prefer this. but i had a hard time picking my o3's back up again, since the differences were so great. does anyone know of any modern equivalent to this frame? i read somewhere that there have been several model cosmetic changes, not sure about characteristic changes, but if it helps, the pj is a dark blue, with copper colored decals (a line around the frame, with copper ace on the left throat) can someone help me find a modern match to this frame?
