OK y'all.  Is there really room in any semi-serious bowler's arsenal for old urethane/soft plastic stuff?

Reason I ask... There is a Black Knight, a Blue Knight, a Red Hammer and Blue Pearl Hammer on Ebay right now.  I'm thinking of getting one or two of them.  The Knights are still low priced with less than a day left and I'm partial to Columbia stuff.

I guess my mortal fear is that a collector will get them and never drill them, and they'll be lost forever, so to speak.  At least if I get one or two of them, if I never drill them I'd give them to someone who would.  I come into contact with a lot of people that would like to get started bowling and this old, cheaper stuff is perfect to start someone on.

And again, if any of you "good" bowlers came across a ball like this, say it was given to you, could you find use for it?  I'm expecially wondering if anyone would use a Red Hammer or one of the Knights.

Opinions appreciated, although I've probably started an argument!

Careful with the Stingray - it's a BIG HOOKING urethane ball. Flares a lot too.
The last Angle LD I bought new on Ebay had a BULGE near the label. I never really noticed it until about 4 months after the purchase when I took it in to get it drilled. It was funny as hell - it went womp-womp-wobble-wobble. I suggest that you ask the seller to make a close-up inspection to insure that it is round! That was a 15# orange LD. The 16# Blue one I bought from the same seller a couple of years ago was a great dry-lanes ball.
Blue Knight would be a good urethane ball. I don't know how well it would polish though if that's what you plan to do with it. My wife has one tucked away in the darkest corner of the garage, and if I remember correctly, it's pretty dull. My everyday spare ball is a polished pearl urethane Columbia Gold Dot. Hard as nails, goes straighter than my White Dot did, AND, it appears to be more durable. Hits pretty good for a spare ball. It fell out of my truck and onto the driveway once - three bounces on the cement and then a two foot roll onto the grass. Three small scuff marks which polished out easily and no other damage. Still doesn't have any tracking. If you find another of those on Ebay - GRAB IT QUICK. Since I just scored an extra one last month, I won't be bidding against you
