i did try to contact longoni cue direct but i got error then i was using there contact form, so i will try here.
i have just go my cue back from Søren Søgaard billiard in denmark, i was getting it upgrade with 3lobite extension. but i think there is some thing wrong with it, it very hard to get in and will not go alway in, and very hard to get out again you have to rock from side to side to get it out. i have made a short x of it, but i will not post it with out permission from longoni cues.
Now I'm afraid my cue is damaged, hoping to hear from you if you can help..
