I think you will like WLP007, especially in an English IPA. It has pretty much become my house strain and has replaced WLP001 and WLP002 for most of my English and American ales. I get pretty consistent results with this yeast everytime. It always attenuates to 75+%, focculates very similar to WLP002, ferments out in less than 3 days, and in my experience does not require a diacetyl rest. It has more restrained English yeast characteristics than WLP002, but has more character than WLP001. I have had no issues with yeast harvesting and repitching. I generally pitch at 66F and let it free rise to 69F and hold. The one thing it may be more apt to do is create fusels since it does ferment so vigourously.
