You've done a great job! A big applause is in order!
+100%!!!!
Personally, I wouldn't like that at all. SR models have a relatively small headstock and big tuners would look out of place entirely, not to mention the overall design calls for small tuners.
True
+1
Not to forget that the design / shape of the SR headstock is something you just don't want to see with those ATK tuning pegs
Then build the SR with a slimmer ATK type of headstock

I think it'd look cool.
I'm looking into flats, but have never played them before and there seems to be this idea that flats only work on certain basses. Anyone use flats on their Ibbys? What do you think about them?
I have TI flats on my SR375F, they are the BEST flats I've ever used. They're nickel with an alloy, very flexible and will last a lifetime, so I'm told by other users of them. They're costly, $80.00, Thomastik JF345 Flatwound 5-String Jazz Bass Strings

I've tried Rotosounds flats, DAddario chrome flats(Too bright for me), GHS Black nylon tape wounds and my longtime favorites are GHS Precision Stainless Steel flats which I still have on my Spector Coda 5XL Jazz bass, they're are so silky smooth to touch(Oooooh Mama) full sounding, smooth, but you can still dial in dirty growl if you want, ice never had to replace a set, but the tension is high unless you go with the light set. My money is on the TI strings, they're worth the extra dough! I really like the tone of nickels plus their flexibility. As soon as I can I'll be buying another set for my Coda Jazz bass.

You can put flats on anything that they make a scale length set for. I run flats on all of my basses because I cannot stand string noise. The fretless ATK has a set of chromes, soon to be Rotosound 88 tape wounds, and the fretted ATK has... Well, chromes, as well... But also soon to be changed out for some labella original '54s.
Exactly

All new basses I get come with round wounds, squeaky strings, takes a different fingering technique but besides that, they don't last as long and they eat up your frets and fingerboard a lot faster than flats. I'll play around with the rounds for 20-30 minutes, just to make sure I'm not missing something on the new bass, then OFF they go, flats on and then I get that nice feeling that says,"Oh yeah baby, this is what it's all about."

Anymore, When I custom order a bass, I send the strings to the build shop that I want setup on it, Flats, and then it's ready to roll when I get it.

But as others will say I'm sure, it depends on what genre' you're playing for which strings you use.
Just picked up a 97 SR800 last night (Last one I had was 10+ years ago) and when I was installing new strings I realized how smooth and easy turning the tuners were compared to the big huge fender type ones I've been used to.
That is one thing I can say about the SR tuners are super smooth but the turn ratio could be better, IMHO. That's really my only dislike for them, not the style.
