Gill I've PM'd you 
Don't know if the info I passed on was any good to you, but thought you could have a look and make your own mind up
Gill,
I went to see Anna on Tues night we started with me showing how I was dealing with Fern recall etc and on lead, she then showed me my mistakes and also used the clicker. She also put a halti training harness on her.
No electric collars and she does not like choke or half choke collars etc. that includes slip leads too
