XXX "utility discs"- discs that come and go out of your bag for specific courses.
So somewhere between 11-15 I can see for a full complete bag. Of course many people have no need for real "distance" drivers so you can eliminate 3 from that.
I want to amend this...
This would be a day at the local course bag. Of course for Tourny's you would want to have multiple of your staple molds. Just going out for a day at the park though I can't fathom taking 4 of a single mold just to have a "backup".
And playing a course you've never played before would probably mean taking all your "utility" discs too since you don't know what you'll encounter.
