I've got a very nice Ron Kilby cue with two shafts. Google him and you'll get his website; he's primarily a carom cue builder but builds some cues with pool tapered shafts. This cue is pristine, with only about 15 hours of play on one shaft and none on the other. Carom-style wood pin, with the threads on the shaft. 18.5 oz and 12.75 mm shafts. Very firm hit with lots of feedback. I love the cue but have not been able to get used to the length; I keep going back to my 59" primary playing cue. If you're interested I'll take some pics and get them to you with a price later today. If you're pretty set on your other option, let me know so I won't bother taking the pics.
