G3 2 Band Silvertip in tortoiseshell would be right up my alley…The recent Beagle brushes showed me how much I like the handle shape, but the knots were not my favorite (although still very enjoyable). So that, plus a few other factors, led me to request a quote for some Eagle G3 brushes in 2 band Silvertip (my favorite hair type) and Super. Unfortunately for me (but fortunately for my wallet) Simpsons came back and said they only had ivory, ebony, and possibly one ruby handle available. None of these appeal to me, so I declined.
After a few more emails I included a list of handle materials that I am interested in and they are looking into it. I thought I was going to be able to avoid purchasing more brushes, but looks like won't be able to escape that easily.
