Use top of keyway tension. That frees up a lot of space below the pins so you can use your picks. There is no way the short hook is too tall when using TOK tension unless you have some of the more evil keyways such as the one used by:

or some of the EVVA keyways:

Other than that, your short hook should not be too tall. Unless the shaft of the pick is too tall, but a file and some sandpaper should take care of that.
