If you do you might want to selectivley harvest those bass with just an "average" body condition and release those with an excellent body condition.

The answer to your question really "depends" a little more information.....

If the body condition of all your bass in that size range are just average or below average then I would definately think about harvesting some of LMB's in that 15-16" size class. If they are all in excellent body condition then I would be cautious on harvesting LMBs in that size class. Is there a good size range of bluegill for the LMB's to forage on? Have you seen any young of the year LMB's since the pond was stocked? Are there green sunfish or anything else in your pond limiting reproduction of the LMB's?
