I see a few potential plays.
1 - Let the turmoil and recent weak data play out and hurt the GBP further, then, assuming elections play out to its benefit, look to get back in around 172.
2 - Play for the bounce off a crudely drawn year-long .
(I think my choice of words reveals my preference. If you play the dailies, I'd sit this pair out for now, but keep an eye out. A lot of potential here for H2 of 2015.)
