Any down sides of going Borgeson vs Firm Feel?

I daily drive a '73 Dart with Borgeson P/S-box.
One thing to consider is the weight(loss) of the Borg-box. It's quite a bit lighter than the bulkcarrier-anchor stock unit.

I had to use 2 hands to remove the old worn PS-box, while I could install the Borg-unit with one hand.
