Well we're talking one pass with a single blade compared with a multi blade razor, I'd not imagine you'll get as close a shave right off.
maybe try for a 3 pass shave until you get your technique down
Yep, a 3 pass shave with feathers will give you a far better shave than your old razor. If you search for 'mantic59' on youtube there are some great instructional guides. He's a legend.
