Blade.
I'm worried sometimes that I switch in the wrong direction on my toggle.
Each to their own of course but I have never had that issue at all. I find it no different from a blade and whilst most are wired in the same way, there have been occasions when either moving a switch up or down or a blade from left to right has been counter-intuitive to what you may expect. Of course you can get used to the way its wired but, like the mini-toggles, push/pull or push/push options to split/tap - never knowing if up or down is split/tap - you have audio clues to help. Not sure if when the switch is up, the PU is on the neck, well its very obvious from the tone of the PU - even with effects. Gibson make it obvious with the bass/treble disc but play it enough and it becomes second nature which is why the most confusing situation is when its wired differently to expectation but that expectation is due to becoming used to a switch working one way from prior experience. If you got used to a blade working in the opposite direction, forward for the bridge PU for example, if you buy a new guitar that is wired 'logically' so forward is the neck, you would find that to be wrong because you have become accustomed to it being different.
Mini-toggles are like light switches - generally only have 2 positions - up or down (or maybe left to right) and these are incredibly easy and I can't see how anyone could be worried about switching in the wrong direction. I don't need to think about light switches, whether EVERY one in my house is up for on or not because I can see if the light is on or not and just use the switch which ever way its facing to turn on/off the light. In one room, I have two methods of turning on/off the light switch so its often changing the direction. If I press up on one to turn on the light but turn it off via a different switch, the next time I have to push down to turn it on. That never confuses me at all in fact I give it no thought at all - its a two way switch and I can see (in this situation) or hear (in the case of a guitar) to know that if I want the light on/off or a pickup active/not or even split/full, I need to move it to change the condition regardless of which way its facing.
A 3-way toggle isn't significantly different from a blade. Both only move in one plane but the switch is mounted into a slot indicating the direction of travel and has extra states whilst a 3 way still only travels in one plane and obviously only has 3 states, however its not immediately clear the direction of travel unless its in position 1 or 3 when you first see it. Gibson again makes it clear the direction of travel with their bass/treble markers making it obvious the travel is up and down. I have 5 PRS guitars of which 3 PRS guitars have Blades and 4 have toggle switches (if you include the mini-toggles too). My HBii for example has 2 '3-way' toggles - 1 for the 3 magnetic pick-up positions and the other to use just the magnetics, add or just use the Piezo. Two of my guitars have a 5 way blade and 2 mini-toggles to individual switch between split/tap or full humbuckers. Just my 594 and Custom 24 have either a single 3-way or a single 5-way and the other 3, the 509, HBii and Special have more than 1 switch/blade. My 594 has push/pull pots so technically these are a form of switch as if they are up hey are split or full HB's when down - not that different from a mini-toggle that could be up for split and down for full but mini-toggles are a bit easier to see the mode/state they are switched to than a push/pull (or Push/push) pot. In any case, they are very easy to work out either by looking and/or hearing the different tones that ALL these switches, toggles, blades, push/pull, push/push etc give when you are using them.
What I struggle with the most is the positioning of all of these relative to other guitars I have. The 594 was the easiest - not only because it was my first PRS but also because I was a Les Paul player so the position and direction was 2nd nature. Swapping to all the other PRS I have, the thing that takes me the most time is getting used to the positions of every thing.
