I read it in detail last night on the train home. I've heard that in the
water the EON doesn't feel that heavy. Wanita may not want something that
big on her arm (she's around 5' tall) but it would fit me fine (I'm 6'3" and
a lot overweight).
So for me, it's not the "heavy" as in "heavy to lift", it's "heavy as
in 'mass'".
With a 2mm wetsuit (or no suit at all), the mass of the thing means
that in order to not move around, you need to tighten the strap a lot.
In a 5mm or a drysuit, there are absolutely no issues.
But yes, it's probably very personal. Try it out.
Your thoughts on carrying a 2nd on each dive? I've been tempted to sell the
Cobra and buy both the EON and COBAL2 (not in same year).
I definitely think that having two computers is a good idea. It's
extra backup for when something stupid goes wrong (low battery, press
the wrong button, whatever).
And even then, a backup often doesn't matter. If the dive computer
fails, just cut the dive short. It's unlikely to happen, so big deal.
But it depends on what kind of diving you do. If you do purely the
"two dives a day, follow the dive master, never even close to deco"
kind of diving, lots of people obviously do it without a dive computer
at all, and that's the kind of situation where you just go "who cares
if it fails, I'll just continue diving anyway".
It's different if you are doing deco diving, or if you're doing
something like "a week of five dives a day, more nitrogen-limited than
air-limited by the second dive".
Because then having a computer fail doesn't necessarily mean just "cut
that dive short, or even continue diving", it can mean "oops, what do
I do about the rest of the week now?"
So it entirely depends on just how bad it is to have problems with a
dive computer. The problems are fairly rare with a single dive
computer. If that unlikely failure isn't a big deal, why bother with a
backup?
(Having multiple computers actually makes the likelihood of at least
*one* of them having problems go up a lot. That's not just because
there are more computers that can go wrong, but it's more likely that
you forgot to set the nitrox mix on one, or not look at one and it
goes into deco and then locks you out etc etc. So because of
subsurface I tend to dive with 4+ dive computers, I've had *many*
dives now where one of them have gone on the fritz. Partly because
I've also been diving new computers for testing).

Your two experiences make Wanita and my 3 years with the Cobra (one
each) seem like a miracle.
But, we haven't pushed the limits and in worst case would have to fall
back on the dive tables (er, dive master).
But, as we start exploring 100-130 I'm thinking I haven't been that
smart -- just lucky.
Thanks for sharing.
Bonus is paid out next week. I'm off to the Philippines the week after
(taking high school students on a 12 day mission trip -- no diving :-( ).
Decisions, decisions.
