Paul, I would first check to see how hard the hammers are. If you can insert a single needle into the shoulder you should be fine. Start with sugar coating the top with a tool that has 5 to 7 needles protruding about 3/16 in (shop made). As I said, use this first to soften the crown then use a single long needle in the higher shoulders. Listening to the amount of attach and body of the tone at various playing levels will indicate were and how much to needle. I would work back and forth from the crown to the shoulder. This way you will not over do either the crown or the shoulders.
