Hi,
i have a doubt about 1680 hands..
many guys change cartel hands on their rep 1680, 5512, 5513 with TC hands because they said are more correct..
but after some research today i have found that 1680 have flat hands not 3D hand like TC or like newer gen sub with sapphire glass..
Phong have these different hands on his website for comparation:

see on the bottom the 1680 flat hand, so maybe the flat cartel hands are not so bed ..or not ?
