I'm about to give my LM Prestige MP to my stringer to restring for the first time. I ordered it with BB ALU 16 and have been very happy with the string and tension (57). However, there has been a noticeable loss in tension since I purchased it two months ago and I have decided to have it restrung even though the strings still look good. My stringer says he has never used BB ALU before. Are there any special instructions (i.e. prestretching, tension, etc.) I should give him when I take the racquet in? I know Luxillon recommends stringing at 10% below your "normal" tension. I just want to make sure he gets it right.
