I recently was experimenting with rolling and found a new start to go fast:

1. You launcher yourself with the dagger preferably as high as you can
2. You switch to a different hotbar slot
3. You hold crouch so when you land you roll
4. You either stay rolling OR you can jump and use the dagger again as soon as you get enough stamina back (only jump when you have enough) Strat 2: you can keep rolling up or down elavation by jumping while rolling!
