Update:
95% back to normal, then...due to the deltoid being where all my arm power comes from now, and it all flowing over the top of the acromion (outer end of shoulder blade), 2cm slice of the bloody thing has snapped off. Hmmm...
So, I have my Trace Elf, waiting on delivery of the BF One10, and I'm STILL in a farking sling. It's been a bloomin' long year so far, I can tell 'ee...☹️
Edit: have spent some time and money buying new bits from @Kiogon and @Obbm of this parish. It eases the pain a bit...
