I agree cam,rapid is horrid in hot weather,but in my experience standard set sets quick enough in hot weather,I'm almost positive that standard is used in hot country's as it goes off just as quick as rapid does in cold climates .
I used standard on a slate job in a orange house in hot weather last year,went of like the clappers
