I used to be in the `no booster needed' camp with 7.5" discs, and ran EBC Greenstuff pads.
Then a year ago I put a booster on because I had a recond one on the shelf.
What a difference! Sure, it stopped before, but in traffic particularly a booster is nice. It stops like a modern car.
I drove Laingy's van last week (new 8.4" discs + pads, and no booster) and it felt like I'd need both feet in an emergency.
If you have the tandem MC fitted and want to fit a booster, just boost the front circuit. Works fine.
