Jayce Question

Hi guys. I know that he's only been out for a short while, but Jayce seems like a strong and fun pick. I find that top is the best lane to take him (less gold/levels in jungle, and less levels bot, he scales well with both), so I've been playing him there when I get the chance. I find that the start of my build is

• Cloth 5 or Boots 3
• Wriggles + Level 1 boots if cloth, double Doran's if boots.
• Sheen (I'll rush if I don't need doran's)
• TriForce

However, I've been experimenting with different builds. Wit's End I find is very unneeded with the AS buff from W in Cannon form, and I'm not sure how I feel about Gp5. Is there any build you guys found does very well?
