I've learned 3 basics braid to leader knots. The FG, Uni to Uni and the Alberto knot. FG is definitely the slimmest but quite certain the longest of the three. The Uni to Uni is not the slimmest but shorter than the other two. The Alberto seems to be a compromise between slim and short.
Can't quite decide which one I like better but one thing is for certain is that all 3 once in a while gets hung up on my guides causing me to backlash fiercely, especially when using them on the smaller diameter micro guides. My leaders are about 5-6 feet long, considering a shorter leader, am I doing something wrong?
