I apologize for the stupid question. In the string instructions, what is it referring to when it says "7T, 9T, 9H, etc." Stringing Instructions: Pattern: 16 x 18 Tension: 50 - 60 lbs. String length: 34' (ss: 9'6") or (18' M’s & 16' X’s) Start M’s: At throat. Mains skip 7T, 9T, 7H & 9H. Tie off M’s at 8T. If one-piece stringing: Start X’s at bottom at 7T. Tie off X’s at 5H. If two-piece stringing: Start X’s at top at 7H. Tie off X’s at 5H & 11T.
