Quark CR2 and CR123 questions

Hello CPFers,



I'm looking to pick up a few Quarks to round out the collection, and have a few questions best suited to the forum's collective experience.



I saw this X-ray pic of the Mini CR2, and it appears that the heatsinking is minimal:







Is this the case in the real world? Is the pic misleading?



Do you feel that the Mini CR2 and CR123 can handle the emitter/driver package, is generally insufficient, or can handle more?



Thanks in advance for your input, folks. I don't own any 4Sevens lights YET, but they seem to be held in high regard here.
