I would go for the Zona,
Mostly because of the HS33s which will start you off pritty good. The frames are quite long but arn't too bad.
The brakes on the T-Pro will soon start to annoy you and you'll want to upgrade to HS33s anyway.
My mate had the Zona and I liked it from what I can remember, I think they are quite good value too.
HS33s are a much better investment than the standar Onza disk brake that comes on the T-Pro mate.
