While disappointing if you are looking for a technical climb, the West Ridge of Pigeon Spire is a mega-classic for its striking positions, spectacular photo-ops, and high quality granite. It falls somewhere in between being a scramble and a technical climb, so if you are proficient on this terrain, it is an easy solo (took us 1.5 hrs round trip), and if you are not, it can be done roped up.
Perhaps the ideal way if you are moderately proficient at trad is to rope up for a few short cruxes, then solo or simul-climb the rest, and possibly use the rappels on the descent. These sections are the first step, perhaps climbing out of the notch, downclimbing the first sub-summit, and the final pitch ascending from ledges around the summit block to the top.
Another thing that makes this climb a great one to include on your Bugaboos list is that it can be a good rainy day climb - although you might want a rope in more places when the rock is wet. There are enough rainy days (or 40% POP) days in the Bugaboos that easier and shorter climbs are important to have on your list to still get out and about, get some exercise, and enjoy the range. The three most popular ones seem to be Marmolata, West Ridge of Pigeon Spire, and cragging routes on Crescent Tower or McTech Arete areas. The South Ridge (Kain Route) of Bugaboo Spire also seems to be a good one in this respect, and can serve as a means of getting familiar with the descent if later planning on doing the NE Ridge - this descent would be very difficult to follow your first time if it is done in poor visibility (clouds, darkness).
