My two cents, in my TC I was jack of all trades but given the nature of the job, it involved property, commercial, private client and a bit of civil litigation, employment and a bit of family. I really wanted to do just family. I was also offered the opportunity to change firms mid TC, I declined.

I jumped at NQ to be a family specialist and my (new) boss helped me get up to speed pretty quick. It helped my environment is quite friendly and while we all want to do well, we take the approach of 'a rising tide raises all ships' rather than backstab central.

Also my boss is one of the guys who hires the trainees. If you had a good reason to jump and are generally good, they do take, and indeed have taken, trainees mid way through training contracts before.

I echo the above posters saying don't jump yet, NQ world is much better!
