I think the 14 ft. Tarpon could be a lot of boat to push, especially for any kind of speed, if not duration. But, I have been impressed by a gal I know, about your size, paddling a Tarpon 14, who usually leads the pack amongst casual 16-foot sea kayaks. Once, we paddled near another group, and I heard their remarks of admiration for that gal, with that boat. She's very fit. Results may vary. I don't know the other boat you mention.
