Wig and Pen in Canberra did a brown ale once, they pushed it through there 'Modus Hoperandus' full of Juniper berries, Cinnamon, Nutmeg, Vanilla some hops and some Truffles.....
Wlp002 english ale is very flocculant yeast. It clumps together like that even on my stir plate. So i think your yeast looks fine.... Or at least it looks like my 002. :-)
The Alc content of your beer will change the extraction of the hop compounds as well.
I find the higher the strength of beer, the less "contact" time needed to get the results I like.
ie. An IPA may take on more aroma, faster, than an APA.
Back when I was doing kits, I did a batch where I put a shot of vodka in eash bottle when priming.
Was nasty at first, so put them away and forgot about them. A year later they seemed to have ballenced out well.
Still tasted like a kit lager, but had an extra kick and some warmth.
I suppose...
Iv had good results with us-05 at around 16c.
100% pils malt (or sub 500g of rice is nice)
PoR at 60min to about 20-25 IBU
us-05 at 16c for a few days maybe raise at the end to help finish.
Nice and clean like a lager but finished in a week!
Its not nearly as nice as my real lagers, but my...
thats how i used to brew before I finally put together my mash tun.
Line the esky, mash, then just pull the bag out and drain.
I didn't use pebbles though! Not sure what they add to the process?
Celli's are great for me, work well on the fridge.
Plus i can pull them off the fridge and attach them to my serving plank o' wood for parties.
Short line to the kegs and I can 'ride' the flow control if the pressure changes due to temp while at the party.
less line coiled up in the fridge...
Thats what I used to do when I did partials. I even used Ice a few times.
Diluting a concentrated wort and chilling it at the same time.
With a full volume boil however, I think the amount of water required would lower your gravity too much.
