I would call that all your eggs in one basket. The sirius may work just fine if someone is nearby and looking for you? The rocket flares are much more effective calling attention to you from anyone even glancing in the direction of the brilliant red high altitude signal. SOLAS rockets, smoke, handheld flares are also very visible in the daylight. The key is a complete SOLAS signal kit containing a combination of the signals. You want to be able to alert anyone glancing in your direction, anyone on the surface looking for you, anyone in the air looking for you. You want to be equipped for that day and night in all weather.
