I normally use Hosa IRG cables which are flat between most of my pedals.  However when trying to use them with my Earthquaker Device pedals the flat head of the Hosa cable doesn't give enough room for the power plug adapter which goes between the input and output connections on the pedal.  

cables I'm presently using

I'm thinking of trying the Rockboard flat cables or the EBS flat patch cables however I'm not sure if I would still have the problem I'm having now with not enough room for the power plug.  

Anyone have any experience with these patch cables?  

Rockboard patch cables:

EBS flat patch cables:
These are what I use and they have far better clearance than the pancake plugs like you're currently using. https://www.sweetwater.com/store/detail/CPE106 .  You can buy them way,way cheaper at AMS though https://www.americanmusical.com/Item--i-HOS-CPE606-LIST.  Great cables for the money, I personalty wouldn't trust those little spaghetti straps you're looking at.
