Matt, why "deco stops" .... was there something special about them that warrented the quotation marks?
Anyhow, suuntos do an increadably irritating thing when they stick and optional 3minute safety stop on the screen at 9ft or so... if thats all its doing, and you dont want to do it then just GET OUT! The computer will penalise you slightly on your next dive but thats all. If it really is putting stops on you then you'll have to live with it.
Best aggressive computer (and that is what your asking for) i have found is the OLD Aladin Pro (the one with 3 contacts and 'dive dynamics' written on it)... if you can get one second hand it will get you out of the water in about half the time of a suunto, the off gas and no fly times are usually about half that of the newer aladins.
The other option is shell out half the budget of africa and buy a VR3..... they are fully customisable and upgradable all the way to closed circuit trimix... hell they even have a game built into them to play if you get bored!
Just one thing, if you do any of what i just suggested and you get bent dont come whinging to me, that mosquito was built by some very clever people, ignore it at your own risk
