You can also add a piece of thin tape around the barrel of the current springbar to see if a larger springbar would make a difference. Bracelet polishing tape is ideal for this purpose.

This tape is very thin and sticky enough to fit into the SEL sleeve without pulling off if it's not applied too thickly to the springbar. You can control the amount of the increased thickness by applying it part of the way around the springbar or all the way around or 1.5x around it, etc. I have a few reps with taped springbars I just left in place since the improvement gained was all that was needed.
