Yes and yes. I also have GR-9's too, the GR-10's are much more comfortable. I have really soft/worn down shoes so my foot actually would sink into the middle of the GR-9's. The GR-10's are flat on the top like the Urban Platforms which eliminates that issue. However, I do find them harder to flip than my GR-9's (probably just me). And if you plan on running double straps you need really long bolts to keep the front strap in place.
