I've read in many posts that flying speed on up and down lines need to be the same. Ok just where is that written? I've read both the FAI and AMA rule books and can't find that rule anywhere. So why are we concerned with this? I understand flying too fast can make your flying looked "Rushed" but come on if my up lines are a bit faster or slower than the down lines who cares? Who cares what the level flight speed is? The judges? They better not be unless they can show me the rule. I understand speed can affect roll rates and such. Just because some world class fliers try to fly this way do the rest of us mere mortals really need to do it?

Opinions?
