I have used many pedals for clean boosts but now if I want a clean boost I just use the solo switch that comes with my Mark V.
I do now use a Visual Sound Open Road for a soloing when I want a bit more overdrive and thickness but other than that I really see no need to waste money on an overdrive pedal using it for a clean boost.
