So many more variables when spraying. Hard enuf when when rolling! A perfect spray job is better than roll&tip. A poor spray job may be worse than a bad roll&tip. Plus, your two-part (linear) polyurethanes are extraordinarily dangerous when sprayed -- not a job for the casual amateur.
I HVLP spray single-part, water-based polys every day & can usually get good results. But the larger the workpiece, that harder that is to achieve -- and it took years of practice to become merely competent.
One piece of advice, learned the hard way: once you find a finish brand that works for you and your situation -- reasonable to apply with the tools you have, nice appearance, good performance -- stick with it
. Changing brands puts you back down on the learning curve.
