I'm finally working through a similar process right now in deciding which time frame I should stay in, weighing the advantages and disadvantages of pure intraday setups and longer time-frame directional trades. I thought I needed to settle upon either/or, but in the process of figuring out which, I've decided upon doing both.
It's a struggle trying to mix time frames in the same market, having conflicting sets of mental parameters in holding longer term positions as well as reading the short term. But after a bit of mental adjustment, I think I've arrived at a good place where I can benefit from both sides -- as it turns out, the advantages from one side cancel out the disadvantages of the other in terms of patience and selection.
