Were definitely not going to block anyone from climbing it. If we have to we will do it at night, work the pitches and get out of the way of anyone trying to make it to the top. Good idea to work some other climbs 1st of equal difficultly and style. I'll talk it over with my partner.
If I was coming from the ground and came upon a party working the zig zags from the top I would not be impressed.
You know I've often thought the same thing. I climbed Salathe in 1981. There was no-one else on the route. I can't really imagine how disappointed I'd be if I'd pulled around the roof onto the headwall to find a fixed rope down from the top and someone working those next pitches.
Edit: I hadn't seen Erik's reply when I posted this.
Gotta go with HarryHotDog, Scott, and Werner. Your plan seems lame. Get good enough to climb it free, then do it from the ground. And if you can't free the zig-zags when you get there, use aid and finish your climb. Then come back when you've improved if you are so obsessed with doing it free. I'd respect your efforts much more as would many here.
BTW: Sandy Ledges is a WAY COOL place to spend a night, especially with a full moon...
My partner and I might give it a go in July. If so, I'll make sure to put the TR up.
As for the rhetorical question about doing the climb bottom-up, it's basically a time thing. We're mostly there to do the single-rope drop off the top of Mescalito--which is a repeat of a trip we did in 2010. It calls for a pretty strict schedule as we have to have people in the right places so some Nose-in-a-day doesn't think they can ATC their way down our rope. Wouldn't say that if I wasn't there when the guy asked last time we were there. I'm pretty sure he was serious...
That, and it's fun as all getout. I've been doing it in between other climbs and for fun for about 20 years. Different level of technical skill--very much like a multidrop pull-down through trip in a cave, or a retreat off a mountain. Mostly steeper, though.
