Pulling back too early and raising the nose-wheel in a tricycle will greatly increase the takeoff distance required by creating masses of drag on the wing due to the high angle of attack.
I know someone who replaced their bungees in their tricycle undercarriage and as a result reduced takeoff distance by near 30% because the aircraft accelerated so much faster on takeoff because the rear was slightly higher and there was therefore less angle of attack and drag on the wings.
On a bitumen runway if I want to take off short I don't pull back on the nose until rotation time which gets me greater acceleration. When I do try to "show off" and do a good short fielder (say an intersection departure) I find myself taking forever to get off because the nose is too high and the aircraft won't accelerate - a common mistake.
Only raise the nose for a soft field takeoff, however that being said, you can of course take some of the pressure off the nose to reduce wear and tear.
