Trade Idea: Adding to VXX May 17th $43 Call Position

I'm finally liking the way VXX is looking, I have liked the way it has looked, I mean more specifically for an add to. The May 2nd expiration is just too close for me to consider adding to, I'll keep it open as it's a very speculative (small) position, but I think the 17th is a better choice for an add to for the position already in place.
