I just replaced the grommets on my RDS 003. I finished and went ahead and strung it up. I had a lot of trouble with the tie off knots (I string 2-piece) and wondered if I was supposed to flare those grommets. Unfortunately I don't know how and it didn't hit me until after I had replaced them that I might need a special tool. I went ahead and strung it hoping that the knots themselves would take care of the flaring. Should I have flared the grommets first? If so, how? Have I ruined these grommets by not doing so? Thanks in advance.
