Howdy - I see lots of reference to turkey wing and leg bone measurements for use along with weight in choosing proper form size. What part of the wing and what part of the leg bone? Before or after removal of ball? Still going on the first of my practice turkeys and the form is way too big.....gonna take it apart and start again. Also ordered a bunch of different sizes and brands of forms to see what works best for me.....start up costs that will hopefully pay dividends in the future. Thanks.
