FWIW, I have Delrin collets, but I often use the strips sold by Gary Langley Cues https://www.facebook.com/LangleyCustomCues
They are not leather, but are very consistent, and grip the shaft or butt well without marking the wood. I can get them to hold the business end of a shaft down to .001" TIR.
Hope this helps
