i prefer my oem honda clutch holder. i think it's discontinued but if you can find one it works great.
I made one as well. I had an old clutch handy. Stacked a couple fiber plates and a couple steel plates together inside the basket to line them up, clamped them together with two small C clamps, drilled some holes through the stack and bolted them to a piece of 1x1 steel angle for a handle. Grips the hub and basket all the way around and I use an impact to remove the nut.
