Sad to say, since I like many of White lab's products, but wlp090 has definitely not proven itself a good yeast in my experience. It actually turned me down on everything it promised. It has low attenuation, not high, it produces a **** load of diacetyl, so it's not neutral and it ferments slowly not quickly! It might be a suitable yeast for some low gravity beers but as far as its advertised properties go, it definitely let me down. I did two beers with it, one low and one high gravity. Both ended up in stuck fermentation stinking like a diacetyl bomb. I was able to clean them up a bit by adding many packages of Fermentis US-05 to both beers and they turned out ok, eventually. Wasn't easy though.
Have I just been very unlucky with this? Does it matter? That's up to you but I want you to know that I am an experienced brewer, I follow pitching rates, I use good sanitation and I don't have anything against White labs' products all in all.
Yeast tends to mutate along the way which is why you can't reuse your yeast too many times. - So developing yeast can only be based upon letting it mutate. Did white labs this time let the base strain mutate too far? Is it a very unstable strain so that some tubes are good, while some are bad? I don't know. But I'm staying away from wlp090 from now on.
