I don't know how your are playing your experiments outside the last bar of your song, but what I would do is experiment in the first few bars of a new song.

Whether you choose a hold or a shot, the drums do a shot.

If the hold or shot does not give you enough of an accent, go to Opt. > Preferences > Arrange. Enter a new number in the Boost shots by, and the Boost holds by boxes.

If you boost the holds and shots, but still can't hear a volume difference, then try another style.

Good luck,
Jim
