I'm a big fan of the Palomar and it's been my go-to knot for lures since I learned it as a kid from an issue of Field & Stream.
In regards to "that piece of tippet I just added is way too long." Are you using surgeon's knots and pulling tippet off the spool, cutting it off and then adding it to your leader?
If so, try making a bigger loop and passing the spool through the loop before cutting. Of course if you are using a tippet spool holder that can be difficult... 😉
If you are using blood knots, try pulling the tippet from the spool, tying your blood knot, then cutting it from the spool. This you can do easily even if you use a tippet spool holder.
Besides the straightness of the knot, other reasons I prefer blood knots over surgeons knots for joining sections of leaders is there is WAY less wasted material (if you leave the material on the spool before cutting) and I can keep my spools in a holder while I add tippet.
The tippet spool holder I use (which I made) holds six spools and where stored allows me to put tension on the tippet I'm adding which makes tying blood knots a LOT easier.
In regards to comments on the strength of clinch knots...
If you shun clinch knots but use blood knots, keep in mind a blood knot is just two clinch knots back to back...
