I personally saw Pia for the first time back in Jan 2015, last Feb 2017 and a few punts in between.
As bender999 says I too agree she is good for the mature punter or the nervous beginner.
I saw her early on in my punting career as she was recommended for a newbie, found her very chatty and gave me lots of advice on punting, including recommending a few others.
Have attempted to see her a few times since 2017, but always last minute/same day, which rarely works for her, she likes to book ahead.
I think she is more suited to the more mature punter or nervous beginner rather than the high intensity young bucks out there. If I had to sum her up in one phrase it would be ‘a class act’.
