BM45 and BM4x4 are very much nutrient hogs, this you have to watch, I've never had these two yeasts even so much as a hiccup at temp fluctuations, but you want to have Fermaid K or Fermaid O on hand, you will want to split the application up into two applications, trust me on this, I've used both of these yeasts a lot.
Now the big question..are you ready to "keep an eye on the kit"? Most kits are tested and the yeast that is most successful is usually selected by the manufacturer.
I can understand why EC-1118 is usually the "go to" yeast for kits, it can ferment a brick, some of its traits are:
The fermentation characteristics of EC-1118 are extremely low production of foam, volatile acid and hydrogen sulfide (H2S) this is a no brainer for Kit manufacturers.
It has a relatively neutral flavor and aroma contribution, this is appealing to the Kit manufacturer, once they balance out the must and give you the steps to take to produce a wine, they don't want anything to compromise that.
It ferments well over a very wide temperature range, between 50° to 86°F, this is a very large window, almost fool proof.
So now that we know why EC-1118 is often found in Kits, it may give you an idea of what you may have to look, and smell for.
I personally prefer BM4X4, it is a great yeast for big bold reds, just make sure that you are prepared to add Fermaid a few times.
