When I was a self-employed contractor several years ago my CPA did it this way for my LLC. 50% of the income went on a W-2 and 50% on a K-1. It's up to each person to decide their own risk level but my CPA was pretty confident it wasn't a big deal as long as the W-2 salary wasn't absurdly low, and my own googling at the time seemed to confirm that.
It's definitely worth it IMO since you're double-paying FICA taxes on your W-2 (i.e. paying both the employee + employer sides).
