I recently led my first real ice route. It was a very moderate WI2 route that followed a left facing dihedral/open book. The route was missing great screw placement in front of me but the wall to my right had good ice and would eat up the intermittent piece of rock pro. I found it a massive pain in the a** to place screws on the wall to my right with leashed tools and I wound up just saying f*ck it and would run it out a bit.
So I guess my question is, what is the easiest way to place screws with leashed tools? I have Petzl Aztars and I'm debating converting them to leashless tools. Would that have any downside?
I've attached a pic of the route in case my description was clear.
