Interesting read on biscuts for your application.

Again a good joiner paired with a skilled user. helps with allignment.
I've read that thread and don't take much stock in it due to the fact that I do have, the PC biscuit jointer. It was sold on the grounds that ease of inserting the biscuit into the slot was easy with room to be a little off on the cut. This is due to the size of the cut being wider than the biscuit. The biscuit is compressed and when wetted by the glue, swells.
Fine Woodworking built a typical dining chair solely with biscuits to prove they do in fact impart a good deal of strength in a joint. Over the years it been my observation that those that don't like biscuit joints state their only benefit is in alignment and make no mention of their strength. I'm also going out on a limb and saying they probably don't have a biscuit jointer. Otherwise their findings would be contrary to their alignment statement.
On the other hand. If you use the Fe$tool Domino biscuit machine. You would have a tight fit and maybe that system would aid in alignment.
CYN. What brand of biscuit jointer do you have? Does it cut a tight slot?
