Thanks for the response, roger456 & DannyW. That's more than I got from the B3 forum. I just wanted to see if anybody else had the same experience I did. I did ask B3 if there was a reason for the difference in hole sizes, but I did not get a response to that. So, maybe it's just me.
But, B3 says they will take care of the problem and they always have been very good before with taking care of any issues I've had, so I'm sure things will work out this time. But, I was just wondering. Now it's time for a beer.
