My taxidermist seems to like McKenzie forms he admits simply because they have such a wide range of sizes it's very easy to find a fit to a customer's animal........I went against the grain and chose a Joe Coomb's full wall pedestal form for my 07 buck (I think its a 94-7222R.) The Coomb's forms came highly recommended by some midwest taxidermists and the couple deer I've seen on them have been outstanding.
Believe me I've been kicking the idea around for quite some time getting into taxidermy. I have a wildlife art background and always felt like I'd be pretty good at it.........don't encourage me. LOL
Good luck with the project!
