Hi Per, I just bought Marsblade for my daughter doing both ice and roller hockey (not received yet) She has Alkali CA9 RPD inle skates She's using Graf Ultra G5 ice skates I'll mount the chassis on Bauer's X50R boot is there any specific setup to be taken care of to achieve similar behaviour with Graf's and Bauer+Marsblade ? Will I have to mount the chassis more centered, on front / back ? Do I need to put extra "wedge" to have a similar "feeling" between both systems ? Thanks in advance Eric
