How many bench Spots?

Many people tell me 6 Spots is more Fun because it keeps the waiver wire active. Should I decrease to 5 Spots? Keeps the waiver wire active and I have 14 rounds? Or 7 Spots for 16 rounds

Some guys say its odd that the early teams have one extra earlier round pick if that makes sense, when we have an uneven amount od rounds

What would you do?
