You are correct! We implemented the 125-style climber between our Week 1 and Week 3 events after a sub-par performance from our original design. More details on that redesign are in our reveal thread.
The Nutrons themselves were a big help, freely offering advice and their own lessons learned. It was a very cool experience.
One of the best things about having one Championship this year is that we got the chance to do a side-by-side climb race with 125. Of course, both teams claim they won the race 
To add on to what Kevin said, we gave the software team the robot a few weeks later than our schedule dictated. This necessitated prioritizing basic functionality - climbing, multi-ball auto - and driver practice before our first event. Tuning the distance shot and Limelight didn’t make the cut. Then after our… issues… at Glacier Peak, the entire time before our next district was spent bringing the new climber online and other minor improvements. Our fender shot at Sammamish was actually significantly better (more tolerant to misalignment) than at Glacier Peak, but it was still a fender shot. Between Sammamish Week 3 and DCMP we finally had enough time to really get the distance shooting dialed in.
The adjustable hood as a mechanism worked from day 1 and was very reliable. We didn’t make any design changes and didn’t have to do any substantial maintenance on it through the entire season.
