I've started using a 10mm joint which gives a nice precise joint, after you've converted you'll see bigger joints as rather agricultural. The downside is that cutting the male without pegs is much harder. There's no 45 degree line, the hockey stick feeds into a tight radius that feeds into the edge of the bullnose. So it's a curve on plan overlapping the bullnose curve and you have to line them up. They don't touch so you're squinting from above trying to look straight down to check. The jig edge is also chamfered to complicate matters! So the question is, what's the best way to line the jig up with the scribed line on the bullnose on a narrow joint? Confession - As a result I'm back to using one peg on the male for reassurance.
