Just one suggestion:
If it has been a little while since your last dive (like more than a couple months) then try to do a dive (or two) before you dive the Grove. I only suggest that because if you and your buddy are not familiar ( = confortable) with current, and not confortable at depth, then it could be a little unnerving. Add in the fact that the first dive in a while usually has a bit of anxiety, and it is a recipe for stress.
I am not saying that it will kill you, but a nervous diver tends to suck air, and a nervous diver will be overly focused on their gear and gauges and remembering details etc, rather than enjoying the dive. On a deeper dive like the Grove, you really hate to be too focused on everything basic (because you haven't dove in a while) and you hate to have a short bottom time.
I have dove the Grove three separate times, and each was good. The first time was just after completely AOW. It was our first dive that deep without an Instructor, and our first dive with a ripping current. However we had been diving earlier that week, so we were comfortable in the water and comfortable with our gear. Still, the dive was rather shorter than we would have liked because of the stresses mentioned above.
However, during our descent, when the deck (and especially the anchor chain) came into view, it was breathtaking (for us).
There are places on the Grove that are not real deep, but you may be at the mercy of the boat Captain, and whatever buoy is available when you arrive on scene. The ship is large enough that you can't cover it all in several dives, so don't try. Just enjoy whatever section you are on.
FWIW
