No deco and dive computers

So, this is a no deco dive within recreational limits on nitrox with a relatively large gas supply. I'd say the dive plan is up to the diver. SB tends to be overly paternalistic at times. Either you're responsivible for your own dives or you're not, I'll go with the former.

I am diving a sunnto cobra 2. I understand all that, I was just makin sure I could go down to 120 for the deepest part of the dive and run my ndl time down to a few minutes left, for example, and then ascend to 100 ft for a few more minutes until time to ascend the line. Basically working the whole wreck using all my available time.

Sure you can. You have a relatively conservative computer. You may want to brush up on gas management and deco theory to make sure you know what you're doing.

I do what you are talking about all the time off our coast. As a matter of fact, we'll usually edge into some deco time depending on what we are doing. But if you run your no deco time down to say two or three minutes and then start up, you should be good to go. Even if you were to spill over into deco by a minute or two that will most likely clear as you slowly accend the anchor line.

Sounds good. Just be sure to reserve enough for that ever so occasional (and embarassing) free ascent...

Not on a Suunto it won't, as soon as it hits deco it will beep and carry on and want you at 6m asap with a 3m ceiling adding to your TTS until you get there. I don't have anything else to add that hasn't been said other than you are doing a no deco dive so stay well within the NDL on your (fairly conservative) Suunto. Yes as you ascend you will get some time back.

Good enough. I had a Cobra several years ago and then switched to a Sherwood Wisdom. The Wisdom will simply clear as you accend as long as you're talking about only a few minutes. It's been so long I didn't remember how the Cobra reacted. Thanks for clarifying.

so pretty much never get down to 1 min left on ndl time
