As always, it depends on the conditions and what you expect to get out of it. If you will have just as much fun throwing plastic, then go ahead, just be aware that it will limit your reaction and your carry, but if the lanes are dry, plastic will carry. I shot 290 last year with an A.M.F. plastic boogie ball that I was using for spares. The oiler went out and the lanes were bone dry and the ball worked great, but the conditions were EXTREMELY dry by todays standards.
Remember, anything will work if the lanes are conditioned for it, after all, didn't EVERYBODY throw plastic and urethane about 10 years ago? They still shot some big numbers then too, didn't they?
