I, unfortunately, do not have any input with the Samson kit, but I actually own the CAD kit. I can basically echo what Greg_L said. It is better for doing live work. They can be used for recording, but your not going to get the best quality out of them. I have, over the time, been substituting mics from that kit out with new mics that I have been purchasing when I record drums. Again, I have not used the Samson's, but I would assume they are comparable.
Do you have other mics of your own? Depending on the amount and what other mics you have, you may be able to use them for drums and then maybe just get a select mic or two to fill in the wholes and record a whole set? Just a suggestion.
