I think for track better for strong and light. Since there's less chance to crack it on track why not just get the best performance?we no pro racer so we dont really feel much.. and comparing the 8MR from RG to taiwan i don think can feel anything also. rims are all bling bling la. sometime i wonder does it justify the value. The EF with 15" regamaster also like meh even on sepang. just buy any rim you think its nice and you really want la. no point buying light like nike air but fugly and everyday moan about it. so... like i said its not worth it- unless you track. but even u track you wanna go for strong rigid rims and not light weight. maybe its just me
