I was going to suggest what XYZ said. Great value in used balls. I don't know about where you are, but here, a reallynice decent looking used ball with about 10-20 games on it goes for $50. Plugging & drilling extra, of course, but if you are lucky, one or more of the holes will fit right and already be drilled in the right position for you, so you may be able to eliminate a plug or two. Even if not, you should be able to get two balls(one for light & one for med or heavy dressing (oil)) conditions) for less than the cost of a new high end market ball. Hopefully, there is a good pro shop there to guide you & set you up properly.
If your old one is worn or "doesn't do anything", you might consider using that for your ball for straight spares.
I would also consider, since you mentioned older guy, going to a 15 lb ball, not 16. Many pro's use a 15. Whatever you lose in pin carry should be off set by the increase in speed you can get with it..........giving you around the same amount of power to your shot. You'll have more energy towards the end of the night, also, along with less muscle and tendon aches.
The Black Widow ball is nice, but if you are not (or can"t) put anything special on your shot (and it sounds like you don't) it would be a waste of a couple of hundred $.
No 300's for me lately, as I am down to just bowling once per week. I do have 3 of them, however, along with a 777 high series. Never got the elusive 800 series, but I have finished with an 807 for the last 3 games of a 4 game set.
GL with your game & choice.
