We did Boott Spur last weekend (descending). Snow is very firm (we barebooted). There were some postholes, but few and far between. We may have added 2-4, but no more - it was firm. There is a section just before it drops into the scrub (on descent) where we lost the trail for about 20 minutes. Lots of footprints in every direction. We eventually settled on the most promising looking tracks, which may not have been 100% right, but got us to the trail proper in short order.
My .02: I'd head into the bowl, climb directly up the Right Gully, up the snow fields to the summit, then decide on your descent route. You will have fun watching the skiers. To me it all adds to the experience rather than detracts from it. Boott Spur is a fine destination for descent, but longer than others. To get to it, you will skirt the bowl on the Tuckerman Ravine trail to a Connector trail (can't remember the name) to get to the Davis Path. This will take you to the Boott Spur Trail. When you get to the treeline you will lose the trail in a maze of footprints (ours and many others before us). Although the last blaze that you see is a double, it marks an ASCENDING turn. The correct path is directly in front of you (toward a knob below), dropping immediately into the scrub (at least that is what we used, and it worked)
I hope that you have the day we had last Sunday! I may be heading up beyond Tuckermans (Right Gully, Lobster Claw, or some other gully) this Saturday if the weather is decent.
