it all depends on the characteristics you want form the yeast. If you do not have temp control, you are really challenged to hit your target anyway.
For a "clean" fermentation, one that has little added yeast character, I suggest WPL001 or comparable. For more character, WPL051. For some of the mild character common to English ales but finishing on the dry side, WPL007 or WPL002 for a little less dry. I also like the Edinburgh strain form White Labs as well. On my Rye Me?, Hops on Rye inspired, brew, I went with WPL001 since that is what the brewer used.
I suggest cool fermentation of 66-67F to keep the yeast contributed flavors and aromas more subtle.
