Its taken me years to understand the differences in flight characteristics between different discs.
Its true you can force a meager selection of discs to do things you need, but, its like a pro ball golfer playing with 2 clubs.
When you have discs that line up like 14 golf clubs, the game gets easier, and way more fun.
I try to tailor my bag to the course or courses I'm going to be playing that day, taking only the discs I need, some specifically for certain holes.
I try to remember when I consistently park a shot with a particular disc, so I can repeat it easily.
I do have my " meat and potatoes" discs that I can always rely on if I'm on an unfamiliar course, and I also carry a " trouble" disc for bad lies, which I find myself in alot.
I usually try to include one " test" disc when I play, there are very few shots I dont have an answer for in my bag, but its always good to see if a new disc can do something better than one I already have.
Right now I'm enjoying testing a lightweight Star Boss. This disc does seem to be a great driver for big headwind hyzers, it carrys a mile.
Lugging a 60 pound brick around a course, full of everything I have in the closet, sucks the life outta me fast, if I'm gonna make it through 54 holes in a day, I need to be lean and mean, so I only carry what I need.
Having light and heavy discs allows you play the wind better.
Its good to have a cheap, expendable disc for risky shots.
Hey, if you can cruise through a tough golf course with just a Roc, then thats all you need.
I need a few more to at least try to keep up, without ripping my arm out of the socket.
I usually end up with around 12 discs, which I refer to as " The Dirty Dozen"
