A yellow legacy leigh was my first ever dunk. She survived. The only thing I would say is that I used a coloured soap to clean the turnlock patch and that wasn't a good idea - it darkened the leather. Also, the plastic sealant around the turnlock patch is now a bit soft. I have read that some leighs did have issues with the sealant, or it may be that the bath and over enthusiastic conditioning that I gave her afterwards didn't help.
I'm kind of thinking of dunking a legacy vachetta now...decision has not been finalized.
