Can’t help I’m afraid but mind me asking what problems you’ve had with the hy/rds? I’ve been thinking of going in the other direction and swapping spyres for hy/rds
Think early hy/rds were recalled; i had a set replaced under warranty when stopping power dropped off a cliff without warning. Replacements worked well for short period I used them before I sold the bike so can't really comment
