All of the Florida Conch Divers (and in this case also the So. Cal divers) are my buddies and my pals, and while I'm not one to rain on anyone's parade, both of these wrecks are advanced dives, and please don't assume that merely having an AOW is sufficient. These wrecks are also very crowded and the currents are unpredictable. It's not unusual to see 8 or more divers on the line at one time doing the safety stop, and especially at the Spiegel Grove, if you miss your original mooring line, you may end up stranded until the boat can pick you up. I have dived the Grove 8 times and I've seen too many people (one is too many) either blow their max depth due to N2 narcosis, run out-of-air at their safety stop, come up the wrong line and get picked up by a different boat, or just get blown off the line at the safety stop and end up a drift. Angie, although a BW at the time due to her pregnancy, has seen it also.
Sorry if I sound overly cautious, but I always rather err on the side of caution, even if it is to merely point out the hazzards of a dive site I know.
