I've done the Speigel grove three times. The first dive I did in 2005 was wonderful. There were strong currents on the surface, but at about 50fsw the current was mild. Vis was great, and the sea's were calm.
The second dive was likely the worst dive I've done in FL. Currents were ripping, 6+ foot seas. The current was also running across the wreck, so if one blew off, well, lost at sea. All this would have been OK IF the vis was good, but it was in the 10foot range.
The Captain on that dive indicated that the ONLY reason he allowed us in the water was because this dive was with the SB Invasion group, and I don't think anyone on the boat had less than 50 dives under their belt and all had experience with current, and depth. Most had done the Grove.
The third dive, just a day later was a great dive. Vis of maybe 50feet, so not wonderful, but good E-nuf. Sea's were rolling maybe 2~3 feet, so not too bad, and current was maybe +/- 1 knot, and reasonable at depth.
So three dives, three very different sets of conditions. I would say that in general the Grove is advance, but not difficult. However dive two was IMO an advanced dive. I blew through my air at a much faster rate then normal. For me, that resulting in over 1000psi remaining, however I blew through close to 500psi just getting to the ball to decend, so recognize that gas managment can become more of an issue when a diver is under stress.
People die on the Grove, and as a certified diver it's going to be up to you to help plan the dive, make sure your gas management is acceptable, and ensure that you are confident. Discuss the conditions with the Instructor, and the Captain. If you or other members of your AOW group are not comfortable call the dive.
As other have suggested DO NOT count on the instructor to make sure that your diving is going to go well. If he has two guys running out of air at 100', that becomes a bit of an issue!
