I did use the Palomar for a while for bottom fishing in SA but then moved onto the Uniknot which I use for most of my general fishing apart from using the Rapala Knot for big lure, plugs and, perhaps, minkies etc.
The Palomar ends up as a bulky knot and can cover part of the fly and can also make it 'swim funny' hence I wont use it.
I also used to use the clinch until it kept pulling free and began using the improved clinch (tucked clinch??) but didnt like that either. This was around the time my mentor showed me the uni knot and I have been very happy with this knot for around 20yrs.
Personally, I cant recall a time when I have snapped off using the uni knot and now wont use anything else.
You can also use it to join two lengths of line!
Try it below
