15 and 5 minute additions vs. Flame out addition

I’m going to brew an IPA this weekend that calls for a 15 minute and a 5 minute addition of Columbus and Galena. Can I skip both of those additions and do a flame out and whirlpool for 45 minutes to an hour? Will i get a better flavor and aroma, or am I better off sticking to the recipe?

The results will be similar - if you have the time to spare on the whirlpool, try it and see what you think.
