disk vs drum pedal effort

[jocko]

Gents, basic disk vs drum brake question - how does the pedal effort for a MANUAL disk brake setup compare to a MANUAL drum brake setup? I've only ever had power disks or manual drums, so I'm missing the middle of the road for comparison. Gonna (eventually) do a front disk install, and am contemplating whether or not to include a power booster in the process.

My current manual drum setup (all stock) really doesn't require too much pedal effort - it's actually a very solid drum/drum original system, but I do want to convert here in the next 6 months or so.
Thanks guys.
