I'm pretty sure most are at least partially coring the front end to reduce mass, but I would think almost any of them would skip that part if you asked.
Off the top of my head, I know Ryan at RAT Cue Repair doesn't core them unless you request it.
I'm pretty sure Schmelke is all solid, but a call to Dave would confirm that.
Diviney's Trans-K is lightened, but I bet if you ask Pat, he'd make it any way you want.

Could also talk to Jeff Prather and either have him build it to your specs or buy one of his blanks to give to the cue maker of your choice. Jeff sorts/grades his stuff and since he was one of, if not the first, to use Torrefied shafts on pool cues, I doubt you'd find anyone that knows more about it.

How to Write Good

1. Avoid alliteration. Always.
2. Prepositions are not words to end sentences with.
3. Avoid cliches like the plague. They're old hat.
4. Comparisons are as bad as cliches.
5. Be more or less specific.
6. Writers should never generalize.
Seven: Be consistent!
8. Don't be redundant; don't use more words than necessary; it's highly superfluous.
9. Who needs rhetorical questions?
10. Exaggeration is a billion times worse than understatement.
