A professional motorcycle electician told me that the mismatch between a standard ECU and the COPs would result in the COPs burning out after 'a certain amount of time', although that time period was not confirmed as being a matter of minutes, or years... Since then I've heard of lots of people who have simply replaced standard type coils with COP with, seemingly, no apparent issues.
I'm certainly tempted with COPs to give a little more room above the rocker cover for stuff, and to increase air flow over the engine too...
