Exactly 3V, any shop of size will keep the very fastest & sharpest around, they just want to eliminate their followers from coming hard on their heels.
Any joint that has Tiger, Baxter, Artie, etc..coming into them, has sharp numbers, and those marks are assets, not detriments to winning.
Show me a book that has only non-sharp action, and I'll show you a book that isn't what it could be..and one that will probably close shop one day.
