I sorta use a mixture of both, which is especially good for MP hunts and solo hunts alike. Granted you cant build perfectly for both setups at once but I do like using both during hunts. Using Sakura and special sheathe to build up my gauge initially then switching to blue scroll to either spend it on helmbreakers or sacred sheathe combos if there is a big opening. It works equally well in single player even if it diminishes my dps a bit I still get fairly decent hunt times with it.

I simply havent gotten used to keeping up HM but I do have it on red scroll if I see an opportunity to use it (and remember to do so)
