Ok, you mention " the old timers did it and didn't seem to have a problem ", ok, what were the old times shooting with??, if your talking old timers as in great pool players in the century, they were playing with top hand made cues that were high quality of the day. Not trying to be smart, but, send me high quality price for a high quality cue and I'll provide a letter right from the cue maker that will state on his letter head paper that their reply will be " why not break with it, you paid enough for it ".
I have heard this from some cue makers who expect their cues to break racks. But, your going to pay for it !!!
