I just bought Rose 1.5s (home).
This is my opinion about 1.5, 2.5, 3.5 - (I play with Adidas Speedwraps)
Rose 1.5 (home) - Perfect court feel, super comfy, looks nice, Cons - ZEROOOOOOO CUSHION. / Overall - the fastest Rose shoes.
Rose 2.5 (playoffs) - Super court feel, perfect comfy with speedwraps (and looks amazing), super cushion . Cons - I don't know why but heel in this shoes is lower to the ground than toes. / Overall - I love this shoes
Rose 3.5 (metal) - Perfect cushion, looks nice, court feel is not bad, Cons - fit is little big in camparision with 2.5 or 1.5 (all size 10), I think that 3.5s is not designed for speedwraps :/ , grip I think is better on 2.5. / Overall - only decent shoes.
