Do you have a steady income of frost badges? I got the off set chest first and regret I bought the T10 gloves. these are(IMHO) better then even the upgraded T10 pieces. I assume you are a warrior? In which case the 2pc T10 bonus can be quite sweet(if you have trouble with threat).
For me it had to be crafted boots and leggins. Badge belt, cloak, chest, trinket (and gloves). Purchase in the order of biggest upgrade first. Which only leaves shoulders and helmet for T10. I would get the 4pc bonus after that since this is a LOT of badges. 4pc bonus can come in handy sometimes. The extra gem slots/better stats are useful all the time.
Following this route also leaves room for chance drops off Toravon. IIRC he does drop gloves and trousers?
