yea, I've used the 5 way and 3 way blade style switches, and the toggle style switch as well.
Personally, I found the 5 way and 3 way switches to be a little awkward to use- I use my switches while playing quite a bit, and I just wasn't able to accurately land on a switch position when moving quickly with them- the feel is slightly different- they don't land quite as solidly in the positions as a more traditional switch does. If your style of playing doesn't involve as many fast switches, I could see it being much better. The flexibility was great, overall, and I did have a minor issue of the 5 way switch getting a little dirty after the install, but some pot cleaner cleared it up. I just found it was hard to adjust to while playing. The 3 way was somewhat easier to use, but I still ended up with the switch sitting between the middle and bridge position quite a bit. Really, it just comes down to playing style and how comfortable you are with being a little more intentional and careful when switching.
I did not need to remove wood with the 5 way switch on my old G&L Comanche pickguard that I put together, but I did need to remove a little bit of wood to get the 3 way into my ASAT Special.
Now the freeway switch that I actually really love is the toggle switch- I have one installed on my G&L Doheny V12, and it's fantastic. I find it totally intuitive and easy to use, and I haven't had any issues at all with it.
Overall, I think they're really good switches, it's just a matter of figuring out what works most intuitively for you.
