The annular booster is more of a drag only set up, so it would suit your needs better than the convetional booster.
The 750 dp quickfuel would give excellent throttle response and is a nice picese for the price, it has a billet base plate and metering blocks it would work well on your set up.
I'd double check the primary accl pump cam though I've seen 2 come straight out the box that were installed backwards which made for a horrible off idle stumble. Goodluck, Charles
