Where to put weight on a B4?

[Charlie Ware]

Hi all,
Just got myself a Factory Team B4.
I've put some ugly 10gram sticky weights all over it, but without really knowing what i'm doing!!!
Has anyone got any good suggestions as to:
Where to put the weights?
How much weight to add?
If I had to buyhe Rudebits/Trishbits Bulkheads, what combination would be a good starting point?

Many Thanks
