this is actually amazing.
the somewhat underwhelming top 30% bump at the top with stock spring suddenly becomes a fantastic buttery & drawn out 70-80% travel bump right before a slight cushion before bottoming out. sound is a satisfying upclack pop. minimal wobble. snappy as hell. bump resistance is brilliant for fast flying typing, as it isn't harsh. absolutely stunning switch.
I hypothesise that this feel could be due to the longer length of the spring, extending the bump, as compared to the shorter stock & heavier halo true springs. I used springs in my 65g r2 zealios from 2016.
enough now go put your springs in your halo trues
