We were faced with this decision early this week.
It was low bar or scale.
Essentially our scaling mechanism did not fit under the low bar (A large cylinder on an articulating shaft. We even went as far to have this manufactured.

We looked at it this way
No low bar = loss of 10pts
No climb = loss of 10pts
But there are other advantages of the low bar including easier autonomous and faster cycle times. So, we decided to forget that climber.
Key word is that.
Since it was only the Monday of week 4 we decided to R&D a new climber in a day. We came up with a telescoping PVC design that deployed a hook.
We are also in talk of making the old climber some extreme cheesecake. I cheesecake worth a couple hundred dollars.
