Master Your Discs, One At A Time?

Like most chuckers, your typical bag or cart is loaded up with an over abundant supply of plastic to tackle any shot on the course. Maybe even shots you won't see in that round. If I think of it in terms of math, my bag holds 18 discs and par for most courses is 54. If you shoot par, chances are you used your putter perhaps 24 times. That leaves you 30 more shots divided up between the remaining 17. If you are like me, you most likely use around 5-6 drivers per round, and maybe 1-2 mid-ranges to make up the last 30 shots. That leaves me about half of my bag feeling neglected.
This leaves me with a conundrum. Do I tighten my belt to carry just 10 discs, or do I try to diversify my disc selection to get each one into the round? I can't bring myself to do either, sort of. After viewing several videos of tour pros talking about what they carry into battle, I have noticed a common trend. Though they may carry in upwards of 25 discs, several of their selections are duplicates. They will have 8 to 10 drivers in their bags but they are only 3 different molds. Same goes for mid-range discs. 6 discs in 2 different molds. Putters are usually 3 of the same mold, and always one or two recovery discs to get them out of sticky situations.
It makes a lot of sense to narrow down your differant molds to a select few. I have found certain models that fit my style and I'm working on mastering them. That way they can be more interchangeable when they need to be replaced.
Another interesting "tip" I heard from a pro who really likes driving with his putters was, play an entire round with just a putter. It was an off the cuff joke and I laughed it off at first, but realized there is some validity to it. I want to now go out and play an entire round just to see how well I can shoot with just a putter. After that, I think I will try the same thing with one driver and so forth. When you reduce yourself to have one option, you find a way to adapt and figure out how versital that one disc can really be. I think it could help.
