But if he wants to have nice accurate elevation profiles to plot on
maps for later use the extra accuracy of the barometric altimeter is
well worth it. It's the main feature that is lacking on my current
GPS receiver and in heavily wooded areas, esp. in canyon areas, the
receiver will sometimes drop back to 2D mode for awhile due to only
getting reception from 3 satellites (or 4 with bad geometry). Then
when it regains a 3D lock the recorded elevation shows a big jump and
makes it look like I fell off a vertical cliff. The profiles can be
cleaned up manually, but it would be better to have the pressure
sensor if this is a major planned application.
An alternative would be to use topo mapping software to get the
elevation profiles. These look nice and smooth but I haven't been
impressed by their accuracy in giving cumulative gains.

I don't use mine often, but if I want to save a tracklog for later
mapping in a heavily wooded area then the external antenna makes for
a more accurate record. I keep my GPS on my handlebars and in that
position my body blocks much of the sky, so it's good to have the
external antenna up higher where it gets a better view.
However the OP has since indicated that he plans to keep the unit
in his Camelback and then the external antenna would be less useful.
