Trouble with climbing solo with ropes is you have to do everything three bloody times over! There is no way round this if you want to keep all your gear,though i do keep searching for a way!
Not having the skills or the inclination to aid-climb big walls i stay within my meagre abilities,and just bumble along keeping my rack as light and multi- purpose as possible.
Some of my scariest moments in 45yrs of climbing have been on narrow windy ridges and hairy loose traverses.So i have worked out the following technique which (albeit lengthy and tiresome) has kept me alive to the present on anything that requires a difficult lateral move to get me out of trouble.
When i reach safe ground i then have the option of "chickening out" and leaving my old tat,retrieving my rope-loop and buggering off,or returning across the gap to recover my gear.
For the return there is a dual option of protecting myself.I can rig up a Via-Feratta system using HMS-Krabs and my super-strong Mammut Industrial slings,or reverse the fall-arrest direction of the Shunt and move back on that,or do both!? (see pic above)
When you get back to the primary-anchor point again STOP! Check your gear and take time to think very carefully before removing the anchor! Is the Shunt in the correct fall-arrest position for the final traverse to safe ground?! Are you protected?!
