In California, we have a code amendment that does NOT allow the design area reduction for QR sprinklers in Ordinary Hazard. However, if you're using the standard unabridged, the area reduction will almost certainly more than make up for the cost difference between sprinklers. If your salon (chemicals, definitely NOT close to Light Hazard, IMHO) or jewelry store has a 10-12' ceiling, you'll get 35-40% reduction and likely save a nominal pipe size all around ...

The easy answer is use QR and be done with it, but selecting an extended coverage sprink gets tricky when trying to satisfy both OH and Light hazard requirements.
