Narrowband filter set

Interesting bundle here on FLO:

Is it worth getting the £265 set with the Hb filter? Never seen the Hb referenced that much. Its only £20 more than the set without and the Hb on its own is £72. Future proof perhaps? What do you reckon please?

My information is that the Hb data is exactly the same as the Ha but about a quarter to a third of the light.
