yes 11 blades tested , but i tried a lot of time to contact you but i have a message that yur box was full ...
11blades is a litle heavier than the 7 blades .... 7blades spools better but not with the same torque ...at high rpm 7 blades seems bettr for me
All i can do is that all the billet wheels are lighter than stock but the 7 blades is the lighter.
