Absolutely! PM me and I would be happy to meet up/show you some of the in's and outs of the hookah setup. And yes, I know you need to know the difference between them. At first glance I knew they where not greater AJ's because I have caught those before, I thought they where lesser which have to be between 14"-22" and no more than 5 in a day aggregate with no more than one of the 5 being a greater, which like you said has to be atleast 28". But indeed they are almacos, these are more football shaped with tall dorsal.
