I wanted to replace the old Die Hard, so figured I would upgrade. I went with the B14115 Braille No-Weight (11lbs. 8 ozs). It is designed for daily use and is the most powerful battery Braille offers that fits in their nifty Aluminum Mount Bracket. Still too soon to tell if it is worth it from a durability standpoint. I do like the clean look, weight savings, and the space it opens up under the hood.
Here's another photo of the installed Braille:

I also installed a PowerTrix Ground Net while I was at it:
