I am building up a new front wheel for my Langster and had a few questions. My original plan is to use a Formula Hub and Deep V rim. What length spokes would I need for this setup? I don't have the hub in front of me to get the measurements.

Also I am planning on using the Formula Hub but I was wondering if there is a noticeable difference between the Formula, or Dura-ace/Phil Wood.

Thanks for everyone's help.

Cole.
