I use a Sherwood Wisdom but consider it the primary tool for figuring nitrogen loading only on recreational dives. For deeper dives and deco dives, I use an Uwatec bottom timer and a slate with a plan derived from DPlan or Palm VPM on my PDA.
On deep air/deco dives I still leave the Wisdom in air mode as it serves as a means to potentially surface early in the event of an abort where I may ascend much sooner than planned. For deco diving the Wisdom essentially uses straight US Navy tables, so even with accellerated deco on a much more consrvative bubble gradient or variable permeability model, it usually only takes a few minutes more in the water at the 10 ft stop to clear the computer. And on the ones where it does not clear and I don't want to wait for it, I still have the option of leaving the water (as I am not relying on the computer for deco calculations at that point).
When I move somewhere with deeper water and trimix becomes a practical reality, it will end up in gauge mode on trimix dives - if it goes along at all.
