In reply to vincentvega:
The Plan is usually is this (bearing in mind that PLans are subject to change).
Split ice pitches into climbing zones and protection zones as far as possible. A protection zone will offer some solid looking ice and some easing of the angle or a bridging position to take some of the strain off. Climb towards your next protection zone and as you near it try to spot where the screw will go. Clear any ice that needs to be cleared from that spot and put a small dink into it with one axe, as a starter hole for the screw. Climb past until the dink is at waist level.
If the plan is working, this dink is in the right position for you to place a screw. If it's not, try to make another one if balance allows. Place both axes well, so that you can take either hand off to rest. If panicking, put a cow's tail and fifi into one axe.
Place a screw, clip, and look for the next protection zone and go.
No hanging around - climbing zone or protection zone, not both. If this is typical Scottish scratching around then all plans are abandoned as a matter of course and it's a free for all for any gear that presents itself, or not.
