Just one quick clarification, I think you meant to say $6 of intrinsic value vs $8. Guess someone REALLY wanted those PUTS.
My thoughts below:
This is a VERY strange straddle and hard to interpret.
The "Ask" bid for all of the July Calls are priced at $0.25 from the $11 strike and above. Thus, it makes almost no sense to me to purchase ANY STRIKE above $11 as they all cost relatively the same. Considering there is obviously a higher probability of hitting $11 then $15 and the cost to acquire both are equal, this action confuses me. The correct straddle purchase on the Call Side should've been at the $11 strike.
