I don’t breadboard much any more, but I usually double the expected rating.
I have a warehouse full of components, but usually can’t find what I’m looking for. Recently, I ordered 100 10k resistors and 2N3904 switches, only to find hundreds on a shelf about a week after the new one arrived.
Maybe you should walk around my shop and just pick up what you need...
Seems pretty reasonable.
Sending a PM shortly... (Just a "funny")
