This route is the easiest way up the tower. Some books describe it as a 5.7+, but even that might be a little stiff of a rating. 5.6 is a common consensus for the route.
The West Chimney is obvious. The beginning of the climb starts on some low angle slabs before you work the final 40 feet through a very knobby chimney. There are a few flat stances with loose rock, so be sure the belayer is paying attention. There are two bolts and chains at the summit. Also be aware of loose rock on the summit.
A few cams should suffice. The rock is not of the highest quality, so tri-cams might be a better option. .75 to 4 inch cams can fit in many places.
A single rope rappell off two new bolts/chains will get you to the bottom safely.
