    Why do you need all these radials for a 35 foot tower? Are you going to be using it as a vertical? Then your question would be germane. If it's for lightning (that's LIGHTNING), it's overkill IMO. 
    Oregon only gets about 5 lightning days per year - not very significant. One ground wire per leg is fine - you pick the length. If it was my tower, I wouldn't bother. 
    Get the N0AX lightning book and read it. Methinks you're mixing up a lightning ground and an RF ground.
