Not sure how the SHP restrictions are an issue, myself.  But it makes sense to stay with the lighter 12" gun IF it will get the job done, and to drop it in favor of larger weapons if it won't.

Thing is, we're already starting to see "gun creep", with the German submissions of 35cm guns to the Brazillian and Chilean competitions and the RN working on 13.5" guns (albeit more howitzers than naval guns).

Oh I agree, its an issue.  OTL the German 12/50 and British 13.5/45 (Course the first units using it wernt layed down till 1910) were aproximatly equal however the US 14/45 was a Superior gun to both (but its first units wern't layed down till 1911 if I remember right).  In the Nverse we end up with people using them on ships with 1909 laydowns becasue frankley well they can... hence Gun Creap, I dont honestly know the answer I do know part of the problem is SHP restrictions but honestly we need them (much as I hate to admit that).  I do wish I could figure it out though casue I realy like 12" guns  ;)

I don't know that you'll really be able to avoid it, especially given the over-armoring that's very tempting to do.  Given that the 12"/50 and the 14"/45 techs become available at the same time, you'd need to have a reason to develop the 12"/50 (the US might want to use it as a BC gun, instead of the heavier 14"/45, for instance).

I just would like to see us try to avoid the Gun Creap that happend in N3... was realy annoying to have to laydown 14" ships in 1909 when some of the greatest ships ever built were being layed down with 12/50s OTL (it led to me building several ships I realy didnt like just to keep up).

France didnt considers this type of cruiser as interesting in the futur.
The composition of the Marine organized around fighting groups consisting of battleships (12 "guns) and powerful cruisers (10"78 guns). Scouting Forces consist of small light cruisers.

The USN is frustrated with smaller cruisers.  At least until turbines make a useful appearance, smaller cruisers suffer from being no faster than their bigger brothers, which makes it hard to use them for scouting (oh, look, you found a smoke plume, and it turns out to be an armored cruiser, which is as fast or faster than you are: either you run away and cannot learn more about what's behind it, or it sinks you).

The other thing the USN is trying to do is fill a gap in it's production line.  1902 is likely to be a pause year in USN production, while the new designs from the 1900 class shakedown and reveal their issues.  The USN would like to wait on heavy ship construction until these issues reveal themselves, so fixes can be made to follow-on units.

I feal your Pain Kworld... What I wanted to build got shot down, and now im looking at a hole in production around 1903.  I also would like to build smaller cruisers (I think of them as CLs but they realy arn't as they have some armor), but I just cant justify them when larger cruisers are curently so much more capable.

more or less where I ended up for a Colonial cruiser, I used 7.5" guns and I think I ended up at 7500 tons light but yeah same problem The diferance in preformance between them and the Gladius type ACs is just to big.

We'll probably be stuck in this spot for a few years, until the turbines start becoming viable engine types.

   (400.00 ft / 400.00 ft) x 45.00 ft x (19.75 / 20.85 ft)
   (121.92 m / 121.92 m) x 13.72 m  x (6.02 / 6.35 m)

You could probably reSS with 120m / 393.7ft

I could, I'm sure, but it wouldn't improve them vs their larger competition.  Shortening them would almost surely drive up their weight, putting them closer in cost to units with the same speed and substantially superior armament and protection.

You have 6 turrets installed on the centerline.
Difficult to instal engines & boilers.
IMO, hard design for the enginers...

Nope, only 3 turrets on the centerline, the 7" mounts are atop the 12" turrets.  Just like on the Nebraskas, or the historical Kearsarges and Virginias (though the historical ships only had 2 12" turrets, vs 3 for the Navalisim ships).
