Chipperd,
If that's the case then you're just going to have to learn to identify them visually. If you're allowed the benefit of a cut-pass test that will also help you. Although, I know of at least 3 production made cues that claim to use Aegis but the problem is, while they do share SOME Aegis properties, they all cut differently. Apparently they are all using different sources. DUH!!LOL.
Anyway, if you're making a list you know that McD. uses Ivorine, Meucci uses implex (or any variety thereof), Pechauer, Joss & Lucasi each have used a form of Aegis,etc. etc. Maybe others here would like to add to the list.
If you're just looking for a good replacement for just about any cue, LBM would be my choice. It would be an upgrade for most.
Addendum
Since I've made reference to LBM here, I've had several inquiries asking if I would sell some rod or ferrules. I have less than 2 ft left and will not part with any. My remaining stock is reserved for my own cues.
However, I've been told that Atlas still has a supply of finished, capped LBM ferrules in stock. Get `em while you can.
Story : A reader of this thread called my shop today while I was out asking about LBM so my ans. mach. fielded the call. He stated his name and proceeded to talk about searching for LBM and so forth for longer than what my mach. wanted to listen so it apparently cut him off before he could leave his number. So if you are reading this, sorry. That's why I didn't get back to you. My ans. mach. has no manners.
