HP100s from Breakwater Scuba - Faber or Worthington?

[anchochile]

Title says it all. Trying to figure out what kind of HP100s Breakwater Scuba rents out so I can estimate my weighting, given that Worthingtons are 3-4 lbs more negative than Fabers.

I called to ask and they said that they're XS brand...but my understanding is that XS marketed both Worthington & Faber tanks over the years.

Their buoyancy characteristics shouldn't be that different. If you look at the specs here, the Worthington specs are listed with a valve.

And the data for the Faber's are without the valve.

When you add the weight of the valve to the Faber's, the buoyancy characteristics of the tanks should be fairly close.

According to your Worthington chart, they're -2.5lbs when empty (including valve).

And this page gives specs for the Faber, also with valve, showing it's -0.6lbs when empty. Not a huge difference, but not nothing. Assuming these specs are accurace, of course.

If your short get the worthingtons

Interesting, I hadn't seen the DRIS chart. It looks like they took BlueSteel's chart and said those are the characteristics with the valve. Obviously one of the charts (with or without the vale) is wrong. Sorry that wasn't more helpful.
