SFQ and PCQ.

I have create parents queue tree. I need some suggestion for using PCQ and SFQ.
On my mikrotik ROS, i have create some vlan for each user, like scheme this below.

Inet------------Public------------------Local
=>vlan1(/30)
=>vlan2(/30)
=>vlan3(/30)
=>vlan4(/30)

=>vlan101(/29)
=>vlan102(/29)

What the best method to control my bandwidth for client.

  1. I want to make one parent queue for vlan1-4 (sharing access) using PCQ on each vlan interface.
  2. What the best queue type, for implementasion for parent`s on child queue for bandwidth sharing and dedicated.
  3. Can i use two queue type (SFQ or PCQ) on each parent or interface.

sorry if my english not too good.

Thanks.
