I've dreamed of a set of these for ages now, am a woose and my whole body's covered in plating.  Just need some handroids to finish off my bionic armour look 

. Personally never tried them but deffinately want them.  Sports bike shop have them on sale ATM
The one thing I would check before buying Is the sizing.  Am a goalkeeper and tried out several sells, addidas, Reuch and uhlsport spined gloves and the spines dramatically altered the size gloves I needed I would usually be a size 10 but even size elevens with spines were tight and restrictive.  Dunno if it will be the same for bike gloves but the frames might restrict movement if not the right size.
