Hi All, Does anyone know about tighter gear ratios for cassettes?

This is my current cassette...

Manufacturer: Shimano
Mfr Part #: ICSHG5010136
UPC: 689228407510
Model: Shimano CS-HG50-10
Size: 11-36
Type: Shimano/SRAM 10 Speed
Style: Shimano/SRAM Spline
Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed
Cassette Cogs: 11-13-15-17-19-21-24-28-32-36
Range: 11-36
Drivetrain Speeds: 10

When I am peddling and want to switch to a slightly harder (or easier) gear, and one switch often feels like a big change. I'm looking for a cassette (or solution in general) that will give me finer adjustments when I change gears so that the change does not feel as large. I don't want to switch the front chain ring either just to get small adjustments. If the first two cogs are eliminated (11T and 13T) that is okay as I don't use those much anyway. Any ideas? Any help is much appreciated! Thanks!
