Texas Resident CHL, what Non-Resident permits would benefit me?

I guess this might be a question more towards frequent interstate US travelers or people that have studied the reciprocity map/laws. What Non-Resident permit(s) can I get that would give me the largest US coverage in terms of reciprocity? I know it's probably a loaded question but you guys might know the answer before I can go look deeply myself. Thanks! via /r/CCW http://ift.tt/2stWtfR
