There really should be no issue with him missing the food by so much, that he gets your hand, which he wants no part of. Follow the advice of the poster who wrote about leaving him alone.
Also you do the "piggy back trick". I have a male who for the longest time went of F/T rats. I did not want to spend 6.99 on live rats, so I'd buy mouse, and have F/T rat ready to go.
Once he had the mouse about 75% down, I would gently hold him with as little disturbance as possible, and put the head of the FT rat inside his jaws as he was finishing the mouse. His swallowing reflex allowed him to take the rat as well, as if it was one prey item. This allowed me to keep him healthy during his 9 month finicky period.
The key is, be gentle, and move him as little as possible during the process. I have not had one regurge, and he is now back on FT rats.
Of course, the safest time to handle any snake is when they have prey items in their jaws. 35 years ago when I worked in zoo reptile house this is how we could administer any care/tests to venomous species and or big nasty guys.
