Hello paco71. That`s very helpful for anyone considering wearing in or around that area -- I wonder would you e mail the details to John in case he misses this, so he can keep it on file for future reference? Some new wearer might come along in 6 months time, and this post will have moved well -down the list and not be easily seen --- at least if John has it on file he can dig it out ... he`s very busy with other things just now....... thanks a lot... Paul.
