Yeah, there are people who can produce good cabs on hard laps, but the amount of time to learn those old-school skills must be huge. I chose early on to use the tools that let me cut opal faster and better.
Harder stones are easier, but I'll still do it the most time-efficient way. I don't think I'm lazy, but just figured if someone could show me in person how to cut perfectly smooth cabs on hard laps I'd try it. Until then, I'll keep using foam backers and flexible laps.
