Yep. I have been fooling around with different shapes and sizes. I have pretty much determined a Shavemac #87 style handle with a minimum 1.5" diameter at the base and minimum 2.5" length. I could easily add .25" to either measurement and be happy.What tools work best fir your hands? Are those tools with long handles, fat handles, thin handles, or something different? Find a brush that has similar handle qualities.
I was discussing this with Rudy Vey when my wife went ahead and bought me the PAA Doppler. It should work for me pretty well. I will use it for awhile to see how my theories work out. Then maybe it will become my travel brush and I will get back in touch with Rudy Vey.
Or, maybe it will be all I need?
I will update this thread as I figure things out.
