I like simple problems like you (I think it's more important to consistently see "easy" tactics correctly and quickly in a game than to solve brain-busters) so I'm expecting to like those books, especially since there are harder problems later too.

On that note, I see that you're (still?) expecting the Jump Level Up books too, which I think you will really like (drilling sets of similar problems, gentle difficulty curve). If I am right about that, it's probable that you will also enjoy the Essential Life and Death series (also from Baduktopia). There's some overlap, but Jump Level Up has a lot of tesuji and semeai problems while Essential Life and Death is purely about the life and death of single groups surrounded by strong enemy stones. I can solve almost of volume 1 on sight (which I don't mind taking an occasional half hour to do!) and volume 4 is supposedly dan level, to give an idea of the difficulty range.
