I've only used the white labs offering but currently have a smack pack of the wyeast offering in the fridge to use pretty soon. The last time I used WLP530 it went insane in my starter and I just pitched the entire thing at high krausen because I was having problems with blowoff. Felt it would be best to keep what I had and dumb the OG of the wort down a little to keep the yeast. I also didn't have a stir plate so I was shaking it. I just finished building a stir plate so I'll be using it soon with the wyeast version.
Oddly enough, the WLP530 finished within 7-10 days and dropped from 1.095 to 1.009. Kept it around 80 degrees. It acted like it wanted to keep going. BUT, something managed to infect it so I tossed the batch. No idea what got it, but there were pellicles. That was a level of pissed off I hadn't felt in a long time.
Don't add the syrup to the fermenter. It's best to add it at 10 min left or knockout, whichever you prefer. It won't dissolve into solution as well unless you heat it into the wort.
