i've never played a silhouette special, but i own 2 axis guitars and love them. i actually have pretty large hands and the axis necks are pretty narrow with good shape. i also have a 7 string ibanez with a wizard 7 neck. it SUPER wide, but very thin and its a 27 inch scale. so thats an idea of the difference in guitars i play. i'd try them both out and see, i know i love my axis guitars to death.
