Find a friend who dives SM and ask them to help you fine-tune. Diving is diving. Trim and stuff is just tweaking.
I suppose the value of this advice depends on what friends you have access to.
I have several friends who are active SM cave divers and use a variety of gear end techniques. I don't expect most people can get good help / advice in the friend circle, or they probably would not be asking these questions on SB.
I will also add, that even w a good instructor, you should expect a leaning curve, trial and error and multiple dives to tweak and adjust. If you are lucky enough to have place good for test dives, this is much bettter. If your paying charter or entrance fees for every dip, you could probably save money by hiring a good SM instructor. ...even if you have to travel.
