Mandel was the best PCA by far, but now, whit lvl 50 12" guns it's crazy, but beware, without the possibility of those guns becomes a worse PCA than Asama, slow, very short range and bad spread.
I do not think it is so difficult to find a middle ground. If you want it to be slower than Molke, should have the same range too. If you want to have a little less range than Molke, should be a bit faster too.
As easy as that.
