Hopback

These days knockout/whirlpool hop additions and hop stands are all the rage, but I was wondering if anyone has any opinions on hopbacks.  Are they a useful in addition to hop stands, or are they redundant?

I built one several years ago, using an idea from BYO, -

Build a Stainless-Steel Hopback - Brew Your Own

but it didn’t work well with my setup at the time.  Now that I’ve done some needed upgrades, I’m thinking of trying it again.

I know DIY follows the spirit of Homebrewings but im a big fan of Blichmanns Hoprocket in this instance.  Its sturdy and can hold 40PSI, so it can also be used as a Randell.  A lot of the DIY hopbacks ive seen leak quite a bit from the top because they dont seal properly.
