a profesional dart can be up to 30 lbs
Edit:
Assuming you are talking about the dart board game, the professionals on average use from 18 to 23 gram darts. Some use lighter and some use heavier. I use 26 gram darts as does Phil Taylor. It all comes down to what you're comfortable with.
So, if this is for the dart board game, there is no such thing as 30lb darts.

A professional dart player's salary will depend on how good he is and how big the prizes are that he wins. The average dart player that is ranked well, can make a salary around 50 to 100 thousand.
The size is around 4cm to 6cm. weight is around 56grams.

I think 24g is most common (not certain).
I am pretty sure the weighted dart would go further, because the extra weight would stop the dart fishtailing, and create minimal air resistance, though if the dart is too heavy it won't go as far.
