Pool deck, which nozzle

I have a pool deck tomorrow, the concrete is fairly smooth and unpainted, but not polished. I’ve been using 1503’s on the usual aggregate, would it be ‘safer’ to use my 2503’s instead?

200’ of hose so figure 1600psi per nozzle. (Surface cleaner)

I’d put, and leave 25’s in. The more you change nozzles the more the threads wear out on the soft metal bar.
