Since we are recommending equipment... I agree with wireless air integrated computers for streamlining but also recommend a backup computer when diving computer based profiles instead of tables. I dive wireless myself and wear a Oceanic VT3 on my wrist and Atom 2 on my chest D-ring. They both use the same transmitter and algorithm. In case of computer failure can switch to the remaining computer to complete the dive with transmitter failure both computer continue to work without the pressure readings so after either a new battery in the transmitter of swapping to a fresh transmitter, I’m back in the water without delay for nitrogen washout which may be necessary with only 1 computer and switching to tables and gauges.
As for the ScubaPro A2... Scubapro is a MARP agreement company and as such set the selling price a dealer can sell for. This makes their gear artificially over priced and a poor value. For those that like their gear the quality is above average but so is gear from many other MAP agreement companies which allow dealers to discount. (Such as Oceanic) I suggest in protest to the price fixing of MARP companies you avoid them altogether and purchase better values of the same quality or higher from MAP companies. Anyone that tells you that you can’t find alternate selections to match function and quality is simply a brainwashed consumer.
Of my 2 kits I use a Sherwood Gemini integrated on my jacket style BCD and a AquaTec Air3 on the other. Personally I consider the Gemini superior to the A2 which I have had opportunity to try. The AquaTec is it’s equal with more features but is hit or miss from the factory and may need tuning before use. Using both an Air Integrated Computer and Integrated Octo is the ultimate in streamlining having only 2 low pressure hoses. One connecting the Integrated Octo/power inflator and the other for the primary second stage.
