All Along the Watch Tower, Need some info!

A friend and myself are planning on heading up to the Bugs this summer for a quick in and out. We dont have a lot of time to take off so we will be watching weather windows closely and head up when the time is right. we live about 10 hours away, in montana so the drive will not be that big of an issue. we are hoping for four days in the range. Our goal is to free All Along the Watch Tower on the North Howser Tower. Since neither of us have been there before I was hoping to get some advice on the route, where it starts, best approach, where to bivy on and off the wall. Our plan is hike in as far as possible on day one, bivy. Day 2 climb to bivy ledge on route. Day 3 summit and start our hike out, bivy only if needed. day 4 drive home. Any and all information that you could give us would be greatly appreciated. Please do not tell us to try something easier, or allow more time, or really anything that is not going to help us send what I hear is an amazing route. Also if anyone has climbed the route and has gear needed, not needed info would be great.

Thanks
