If you allow for higher output machinery, the GB/CB/1905 is a supership

I adjusted the machinery date in Springsharp, so as to get a higher SHP/ton reading, and with that, the GB/CB/1905 works really well. I was actually able to add armor, and go with my revised speed of 33 knots. Frank Fox's advice was to have more and smaller caliber guns. David K. Brown had a similar comment, as well as suggesting that the belt be increased to 6in. I have posted on this subject before, but this is the first time that I have achieved a satisfactory design (essentially by cheating on power, but not unreasonably: 26.84 SHP/ton).
