Another excellent source is the British supplier Foxy-Tails (www.foxy-tails.co.uk), which sells online via eBay and readily supplies U.S. tiers. The company's proprietress, Sue Billows, says it offers three species of "polar" fox, in quarter, half or full tails. Blue fox is a shorter, coarser hair with some darker coloration in the guard hairs. It makes excellent short wings and feelers, such as on Crazy Charlies. Shadow fox is also shorter, but it is pure white and dyes to vibrant colors, and it has a very silky, fine underfur, excellent for tails on small baitfish patterns. Finally, the cream of the crop is marble fox, with soft fur up to 4-plus inches and nearly translucent guard hairs that make excellent larger-profile baitfish. All grades are useful and offered in a dizzying range of colors.
