I found this blade is really solid for CH.Pen and not so head heavy in mine. To make this blade durable when changing the rubber, use 2 layers Stiga Attach Power Glue. The glue is specialize for this blade. This blade can do anything. It is one of the best blade I had. For me, it is an OFF+ blade. Use it and no need to search other blades, except if there is another better blade.
