You're welcome.

As far as hedging correlated pairs is concern, the safest pairs to hedge are eur/usd and usd/chf, though low volatility and lesser swap gain, those are the safest.

You can add gbp/usd to the 2 currency pairs I've mentioned for a little more volatility. I personally don't hedge the 3 major pairs, because sometimes 1 of those pair will go off the range, and the hedge will be off, like what happened during mid of March, the cable (gbp/usd) was heading north but the euro (eur/usd) was just ranging for days and swissy (usd/chf) was heading south. It is completely out of hedge.

It is also very important to pay attention to fundamentals when hedging. If you heard or found information that carry trade is unwinding (like last Feb. 23, global financial turmoil) stop hedging.
