I won't limit the decision to only DIN but will take it into consideration. Along with the pros and cons of AL80 vs Steel Tanks for Sidemount.
I am primarily concerned with finding a operator that has agreed in advance that sidemount is OK. Can pick the group up at the Sabor pier. Does not make more experienced divers cut their dives short due to other customers with high SAC/RMV's. Charges a fair price compared to the rest of the market.

Now those are good ideas.
I would say, most everyone will pick up at Sabor as it is on the way to the southern sites. Can anyone think of an OP that would NOT pick up at Sabor?
MOST of the boutique ops will let you dive your tank. (Or in the case of Aldora, I think they surface together on steel 120s, so it is STILL one of the longest dives.) I am at a loss to think of more ops that group surface normally? Dive Palancar? Dive Paradise?
Price might be your best place to start? Get some quotes, then ask your other questions? Pricing if often relative to the number of dive days and people. If you have a group and a few days, maybe you can work a deal?
