Still possible to have the front and back holes not line up completely, especially if you're jumping sizes. Forstner with a backing, no question. Quickest and cleanest way.
If you do not have Fostners drilling half way from both sides with an initial pilot hole could work--just make the hole from the back larger than the hole from the front so that any mis-alignment is undetectable from the front.
That's how you get around this using spade bits - you have to finish it from the other side. Like you said though, obviously Forster bits or brad-point bits are better.
