I have everything drilled that I buy. I do buy way more than I need. Part of my enjoyment in bowling. I still buy far less than some people on this site, but I buy more than the majority of people in my city. I dropped to 14lbs over a year ago. My wife moved up to 14 and my oldest son throws 14. Now I can just give them some of the balls I no longer want before deciding to sell them.
As for the topic, I try to make use of everything. Even with bowling 4+ leagues and tournaments, it's still hard to do. I picked up a used Critical in a 2 ball deal when I got my Hectic. That ball has mainly just been sitting in a bag. I don't use my Code Black all that much. The Match Up Solid hasn't been seeing much action. I'm sure there are a few others. Some I will mainly use in practice - not that I do much in the fall/winter with all the league bowling.
