I've used the DGs for years with excellent results. I know you're working in 00 but 0 gauge ones are a better bet. Dimensionally they are the same as the 00 ones but are etched on slightly thicker brass. This means that the folds do not need reinforcing with solder - making them easier to chemically black (paint will gum them up). The extra thickness also improves the fit of the delay latch which on the 00 ones can drop down the side of the hook as it's quite a loose fit in its hole.
