Bought a new cue

3 weeks ago I bought a new McDermott g229 at the philly expo. I love the look and feel but the 13mm is was a killer. I shoot with an i3 shaft. This morning new g-core shaft was delivered to Mcdermott to get turned down and a new tip. I can not wait to get it back. The guy from the expo will be personal calling me to go over everything.
