I wonder what the velocity of that setup would be? My gut feeling is, do as others have said... keep the shots to under 20 yards, make sure he's got it all together and can make the shot... shoot BEHIND the shoulder... a small broadhead like the Montec Alwine mentioned or a smaller 2 blade (stinger?)...
I have been listening to some accomplished trad archers for many years and know that a 40# rc or lb will get the job done on deer or elk with good shot placement! Of course, that is 27-38 inches of draw... but with the compound, he's probably getting close to the same arrow speed as the recurve at the higher draw length, if not more?
I think the biggest question is if he can make the shot... but THAT...you wont know...until its over.
Keep us posted!!
