Before you buy a stiff draw cap,
you can place a piece of tape, like masking tape, over the hole.
Then use a needle or toothpick, sharp edge to poke a little hole in the tape over the cap hole.
Try it then. You can make the tape hole bigger as you go along, to test if you really want a stiff draw cap.
I did this when I first got mine, and after a little while, I just ditched the tape.
Most people wind up preferring the stock cap, YMMV.
Great idea!
