One of the findings that keeps my hope alive is the carbon dating of not only dinosaur soft-tissue, but lots of other stuff, like coal. I realize that mainstream geologists tend to sneer at this, saying there have to be errors, and I know that sometimes people identifying themselves as creationists have done sloppy or even fraudulent work (mainstream scientists occasionally do that to, even famous ones like Mendel). But just as you probably give mainstream scientists the benefit of the doubt, I tend to do the same for creationist scientists.
I realize I'm stepping in without a lot of background as to your critiques but generally speaking a couple important points (others have probably already made these).
When dating something it is important to use a radiometric couple that is appropriate to the age. So if you do a measurement and the amount of daughter product or parent isotope is too low to be in the "detection limit" of the mass spectrometer you can't really rely on the data. This means that certain isotopic systems can't really be used for certain ages. So for instance, using 14-C to measure the age of something that is many millions of years old would probably not be appropriate. Even if one could generate a number.
A good example of how this technique has been abused by a Creationist scientist is the dating of the Mt. St. Helens Dacite by Steve Austin. Apparently Austin sent his samples to a lab that noted the detection limit of the instrumentation and his data fell outside of that stated range making his results meaningless. But you will still see Creationists take this measurement as a proof that radiometric dating has serious problems.
The only "problem" is that a Creationist wanted to misapply a system and regardless of proper lab techniques he abused the data and presented it as valid.
