I have been quite satisfied with my favorite shoe trees, the Woodlore Epic twin tube trees. But I splurged when I ordered the whiskey Harlechs and ordered the standard C&J trees (mainline I think it was). I was shipped the older mainline version with the single tube trees, not the twin tube new trees that have presumably replaced the single tube version.
My comment is that I am amazed at how well the C&J trees fit my Harlechs. They also fit the Conistons really well. Very tempted to order a couple more of these. I couldn't understand why anyone would spend that kind of money on shoe trees. But maybe I do now.
