BiS for BRDs in the current content

I wander if I should replace my Gryphonskin Pants with Bard's Tights or is it better to replace my Darklight Belt and Ring to Hero's?

The pants are still going to be the best upgrade you can get per piece. However, get the upgrades in the order you feel is necessary. You're eventually going to grab everything that is an upgrade in the process anyways. I personally am going for the ring next after buying the belt last week. I might even go as far as to get a Gryphonskin bracelet to use in certain situations over my allagan bracelet. I really prefer having mass amounts of crit but thats just my personal preference, whether it's better or not is totally up for debate.

Thanks for the response
I also like having mass amount of crits as well, seeing Bloodletter refresh on almost every GCD is such a joy.
