I certainly would not be in a position to know. Hash settings have been one of the big arguments over the years. I was just passing on what i was told. Regards, George. Tho i tend to agree that as long as u dont set it too high, the gain by increasing it would seem minimal to me. It has been argued by some who u think would know that if u have it, use it. Ive heard so many conflicting thoughts on this subject that i have about given up trying to figure out the right approach. But your thoughts do make sense to me. Regards again, George
