Are you asking what our preference is, whammy bar or not? Or which brand do we prefer? I like my whammy bar and like my Schecter Banshee Elite and my new C1 FR-S. The Elite, I rarely have to retune it. The C1 I have to slightly retune it almost every time.
My Suhr Classic HSS holds tune remarkably well. Same for Tom Anderson Guitarworks. My strat also holds tune very well...and I'm a total wiggle stick wanker. The secret is in a properly cut nut and setup. Locking tuners are a plus too...preferably staggered.
There are good videos on YouTube that show how to keep a strat in tune through wiggle stick wankery.
Of course the ultimate is a double locking FR type, which isn't as hard as some make it out to be.
Double ball ends aren't the quickest to change because of the 40:1 tuners. But no clamps, no wrenches. And with a locking nut you need to use the bridge's fine tuners, so there's not that much extra tuner twisting.
I second a parker, it's got singles but for quick changes, holding tune, they are hard to beat. My PRS CE 24 and Santana is a quick change, stays in tune no issues. I really like the PRS trems, goldy is getting a lot of play lately.
1977 ibanez futura with a floyd rose frx double locking trem unit ,
1975 ibanez destroyer with a 1980's kahler locking trem unit complete with hard to find chile pepper tip .
the pickups at the bridge position are dimarzio crunchlabs .
I've always preferred locking type tremolo equipped guitars (Floyd, Schaller, Lo Pro Edge from Ibanez, etc) for as long as I can remember, a personal pref thing, it's just part of my playing style I suppose (thank you Jeff Beck, Greg Howe, Satriani, Michael Lee Firkins, etc), so much so that I've even scoffed at NON locking trem guitars, I mean to me changing their strings is easy enough and they stay in tune so well that it doesn't make sense to not take advantage of them.
So I was skeptical when I got my Suhr Modern Pro loaded with a Gotoh 510 trem and locking tuners. But that was an eye opener, turned out it works every bit as well as my trusty old Floyd's and is even easier to load fresh strings. Many Charvel's come with the exact same setup now too (Gotoh 510 + locking tuners). I'm no longer a Floyd snob lol.
