Ryan, You have not flown much HLG if you are thinking full flying stab. Especially in Reno.
Large stabs are good in some respects. Mine are quite large as are my rudders. They are also much thicker than you can imagine also. there are reason for this. However they are quite light. My bagged foam ,thick , 0.75 oz cloth with CF reinforced rudders, come in at 11 grams as do my very large stabs. they can be made to weigh less, or more depending on the epoxy layup, but most of the weight is in the foam not the epoxy. None have folded on launch. Except for those people who like to fly uncuopled rudder-ailerons, most are coupled in some fashion. Many also put exponential in each surface as well as differential, depending on flying style. Flying stabs might be great for tweeking the decalage, but I do not like them becasue they stall at the slow speeds, and stall recovery is not good. While flutter may have to be taken into account, there is also the weigh penalty of the stb controls.
