Hallertau Hersbrucker - AA + Flavours

[Kp2]

Here's a quick dum question for a sunny afternoon.

I have Hallertau Hersbrucker at 6.6% aa. But I need Hallertau Hersbrucker at 2.0% aa.

At 2.0% aa, I will need 58g in 23L (for the bittering 90min). So after the ajustment ( 2/6.6)*58 = 17.57g.

I know I will get the bittering, but the question is what about the other flavours ?

Less mass would less flavour ? Any thoughts anyone ? Thanks for any input.

Add smaller amount at start as first wort hop (running wort onto them) to get the most flavour from the bittering charge, add at 10 minutes from end for flavour/aroma checking on IBU additions and then chuck the remaining weight in either at flame out/end of boil and steeped for half hour as aroma hops which will contribute a negligable amount of bitterness (no rolling boil to move them around) but all the aroma.

What's the OG etc

Cheers for that LancsSteve. Reading back it looks like I forgotten the (very) basic understanding of hops use. Ended up just throwing in the ajusted bittering amount anyway. Why the problems? different text in clone Brews 1st compeared to 2nd copy and failing to read right. And then I started to think, Um And then the cry for help.
The beer was BarBar and OG 1.080 ish. And the whole house smells like a beehive, but at 2:00am this morning, no wife to tell me off.
Next time I will have a go at changing the hops times. Spread it out a bit more to get a "balanced bittering" effect in the first 30min.
