OMS vs NAS vs Others

But it still looks good!

easy to extent them
I don't think I've met anyone with OMS wing that hasn't extended the dumps

I've added a piece of bungie to my harness and run the standard length dump under it so the bobble at the end sits exactly on my collar bone. I can find it realy easily now whereas before it was impossible.

I have also recently moved onto an OMS wing. Seems that a lot of people in my club now have OMS wings (is this the new Buddy?).

Extending the dump string is easy and makes it a lot more accessible. I have also reversed the wing and swapped over the top dump and inflator so that their connections are now on the back of the wing. This then routes the hose over my shoulder and allows me to dump whilst horizontal without having to rely on just the bungees to squeeze the air out.

I am still trying out various combinations but will let you know if I find any problems with this setup.

<font color='#000080'>Right then. Interesting. I think the test drive is the only way to sort this out. Don't know yet if it will be test drive this weekend, I am now a mobile Digger again, thanks to a shiny new car (well, 2nd hand, but still shiny) so might be out and about playing with gear.

I'll pop it on the Planned Trips if I'm planning to go play, and you guys can comea long and have a look at my evil plans! Evil, I tell you!

Digs.

<font color='#000080'>Hi,

why do you want so much lift?

<font color='#000080'>The twin 12s, steel stages and all the other gubbins that I need on a dive tends to add up a fair bit, and the TekWing was too marginal for that. It just wouldn't float it well enough. The TekWing was 23kg (50lb ish)and I felt it needed to be a lot bigger, then again without trying all the options out I'm not certain.

Is there a sensible option with less lift capacity that I should try? I've not found many wings that are in the 50-80lb area. The OMS is 100lb, which I think is too big for my needs right now, but may come in useful if my diving goes the way I'd like it to, with longer bottom times and some deeper stuff I'd be onto 15s for. And being bungeed it's not a major problem to have some spare lift tucked away.

Any opinions are appreciated, especially from users of larger wings. So far it's still OMS vs NAS though. The Diverite looks ok though.

Digger,

I dive the Diverite Superwing, 15's and stages and I still tighten it down a bit.

<font color='#0000FF'>hi digg
forgot to mension super one diverite copes just fine with twin 12L 300bar CYLINDERS

Thanks for the tips on the dumps, I like the idea of reversing the wing and then swapping over the connections to route the dump off the back of the wing. &nbsp;Looks like I'll be going for a fourth reconfiguration tonight then . . and it hasn't even been in the water yet.

Diggs, &nbsp;I was in a similar situation with my old wing - a dive rite rec wing with 50 odd lbs of lift. &nbsp;For the twin 12's and the 7l ally stage, theres enough lift on paper, but I just wanted the comfort factor of having plenty in reserve, so decided to upgrade to the bigger wing. &nbsp;The OMS is huge and well over what I need now and long into the future. &nbsp;But the peace of mind that I do not need another upgrade if / when I do my trimix ticket was, in my opinion, worth the money.

I was originally looking at buying the Custom Divers TBD wing from the show, but couldn't find one for the right price, then I stumbled on the OMS. It was so not DIR that I just had to have it.

Hi

Although their 'innovations' are virtually DIR copies

We wannabee DIR!!!

Funnily enough I was at Stoney Friday last week and met some guys diving CD wings. These were the big double bladder things.

They saw our DIR setup and came over to chat, and one commented something like, 'Thats one hell of a wing, what size is it?' This was my 40lb wing! Makes you think just how they measure lift as surely the CD wings should have been a lot bigger.

I usually need just 4kg V-chunk/tailweight with my twins in freshwater. That is a 400gm Type B Thinsulate to sink and results in me being neutrally buoyant at the surface with 35 bar. I have tried this 40lb wing with an extra 4kg on my belt and a full ali stage and full twin 12's. I still had lift to spare. My wing was not full.

Next time I might just take some more weights with me and get Mark to pass me his stage so we can see what the actual limit is. I do think this lift thing is so overrated. Its alright weighing your gear but you have to offset that weight against the buoyancy of you and your insulation and TBH that is a lot of positive buoyancy.

However you buy what is comfortable for you. The downside is that you then must compromise in other ways. Buy a wing with bungees for example or have a wing which will wrap round the tanks too much. This may require more weight or different ascent style as you will not be able to empty it from a horizontal position because the highest point of the wing will be too far away from the dump.

Kindest Regards
