Hello, I'm new to the forum but not to the game. After a 15 yr break I'm starting to play a few times a week again. I have a Mcdermott D21 that I purchased new in the late 80's. It is in excellent condition and plays great. I'm looking to either upgrade this with a new LD shaft and send it to Mcdermott for service and a leather wrap or just purchase a whole new cue. I was looking at the Mcdermott G502 which is around $450. I'm also considering buying my friends Predator 5K with 2 314/2 shafts in perfect condition for $500. Going to shoot with it later today to see the difference theses new LD shafts make. My question is am I better off keeping my Mcdermott original and possibly selling it or modifying it. Are the older cues made better than the new ones? Also, what is a fair price for the used Predator 5K w 2 shafts? Sorry for all the questions and the long post. Thanks in advance for any advice...
