Been meaning to write this up, soz.
Its basically as rob says.
Arrive in Fingernail Chamber, Window down into balcombes way is on your left is rigged.
straight ahead, in-situ rope rigged up over boulders leads to W-Highway passing hanging rope, this is the rope up Vortex 2.
Up this leads up, then across a rising traverse over a muddy boulder pile. Rope ends at a huge bedding plane very reminiscent of the far flats in nettle. The rope is indeed rigged on old plate hangers with rusty mallions. New Resin Bolts are in place ready to be rigged on. However, I suspect a set of bolt croppers is needed to remove the old mallions, and stainless mallions needed to rig the (new?) rope to the Resin Bolts.
When you arrive at the end of the rope, ahead and slightly to the left is a crawl in the bedding through to Vortex 3, A blind, 30m deep pot.. see

To the right, a flat out crawl in the bedding leads shortly to Vortex 1, As Pitlamp says, there are just 2 manky old spits at the start of the slope down into Vortex 1.
The Crewe Rigging Guide should not be believed, as it suggests that this pitch is easily rigged with one re-belay. New bolts are needed.
A flat out crawl in the bedding traverses the left edge (somewhat un-nervingly) of Vortex 1 round to a small climb down (6 foot) into a small boulder strewn chamber, across which is the start of another large Pothole, This is Balcomes Way Aven, again, there are only a few manky old spits. These are in fact the ones used to climb the aven originally.
Pitlamp, Am I right in thinking that this was the original way up (it was the only place I could see evidence of climbing bolts). It would explain the Naming of the pots, as then, in order its up BW Aven, Vortex 1, then 2 then 3.
Back down in Fingernail Chamber, as you drop though the window on the way to balcomes way, you pass under Vortex 1 which does look like a fine aven, then down another little rope and under BW Aven which looks even finer.
I think it would be a great addition to the already splendid SRT antics to be able to go up Vortex 2 and then either drop down Vortex 1 on a pull through, or BW aven on a Pull through.
Wouldn't mind getting involved in the re-bolting of it either.
