Mmmm,
Not doing too well here for a quick definitive answer but appreciate the suggestions!
Thought the video was online but might invest in it and yeah, found that page, thanks Jonnied, but wasn't sure how well it translates to the UK and our species - probably quite well but as it says on the page "Different regions of North America have different subspecies and each of these deer have their own hair characteristics". Maybe being overtly fussy but unless I can get down at the right time I have to give instructions and it seems a shame to not get the best bits from a kind offer.
Thanks anyway folks,
Andy
