Takai coil VS Blackops Coil

Hey guys was just curious about the couple different coil set ups for my GSXR. I def know that Takai the real deal, SSB did complete section on them and just adding them gives ya the extra ponys and torque just by swapping them but in the process of searching for them i came across a set from blackopsmoto.com and few other places. They got alot of buz for and from the supercross and motocross guys and make  sets for the rockets but i have not found any i guess "dyno" proof that these coils do what they claim. And with Takai coils tested and have dyno numbers to show they work. Was just curious if anyone had ever heard of these guys or tryed them or know people that have or anything. Looking for nice set of performance coils for my bike and dont want to be caught off spending that kind of money for a good set and get ripped off by immtation set. Just curious whats out there, if there is better set than Takai that i havnt found or what not. Thanks for the comments and thoughts guys.
