There are a couple of other factors that could be making a difference. Firstly the on-sight bit - can you top-rope onsight (I know, I know) 7a? Being able to climb 7a with beta would be quite normal for someone who can lead 6c+ onsight.
Secondly when you top-rope are you undoing the clips as you go? If you're just top-roping with no clips in that can make a significant difference in difficulty. Clipping (particularly if you're putting the draws in as well and have to pull up slack) involves hanging on one arm which you otherwise only have to do momentarily when climbing on a top-rope. You get a significant extra pump doing so on difficult ground.

Yep, get Dave Macleod's book
