I use the ESV for my personal study and will usually use the NASB the majority of the time from the pulpit.
A big influence for this was being at SBTS where a majority of the profs used the NASB, and Dr Mohler was involved in the ESV publication.
As a third, i would say either the HCSB or the NIV; both are toss ups to me.
my 2 cents worth, feel free to keep the change.
