RE: Backstrap vs tenderloin
I'm with the majority! Tenderloins are inside the ribcage, Backstraps are larger and run along the spine on the outside of the deer.
I'll never get shafted by the butcher, because the T-loins and straps never get to the butcher shop!
BTW, some people don't realize that there is another set of Tenderloins inside the deer between the front shoulders! They are not as big as the back set, but on a good size deer, they are worth the effort to get too!
