I bought some red monkey fist balls from this guy on eBay. They seem pretty good and feel right in the palm, thumb and finger. He's got some more up for auction at the moment...

Geoffrey,

Make sure you check out Frank Starsini's site. There are some great Monkey fist ball there.

I was considering these balls, but I had a few Q's:

Are stacking moves difficult with these? (Is there a lot of friction between the cups and balls?)
Are they heavy? How do they compare to the weight of mouse balls?
How big are they?

Thanks.

There is a lot of friction with leather monkey fist balls.  Not with our new nylon balls.
They are lighter weight than a mouse ball BY FAR!!!  But heavier than average.

If you want real heavy, we make the nylon monkeyfist balls from mouse balls too.
Just a different product.

That's specifically what I use. I love the heavy mouse balls with my large cups.
