If you got the razors from SRD they WERE shave ready!
Did you strop BEFORE you shaved with it?
I ask this because you said they were always rough to shave with.
You could have dulled it from your stropping?

With a properly sharpened blade there should be NO tugging or pulling of ANY kind.

This most likely is technique related.
Being either:
1. Improper Stropping
2. Improper Angle
3. Improper Skin Stretching
4. Improper Honing
5. A combination of ANY or ALL of the above.

It is a BIG learning curve to SR shave, plus put in the learning curve to maintain your razors and you can see how easy it is to have less than desirable results!

Keep at it and keep working on proper technique. If you can find someone to mentor you that will put you WAY ahead of the pack in the learning curve.

Good Luck Bro!
