Tbow or Shadow?

I have recently been doing a tbow rebuild. I started the rebuild back when the Shadow and tbow were closer in price (shadow was about 1.6b I think). I ended up going with the tbow because of the lesser running costs and it being more effective with rag gear. Now that the shadow has dropped so much, I can afford it with full ancestral, crystal and bowfa and probably a decent melee setup. I think I am just feeling a little stuck with the content I can do with a tbow.

Anyone else done something similar to this or anything along these lines?
