Arcal, - I dont know who you work for: some companies have a very strictly defined programme of what they want their pilots to cover during recurrent training, and there is like you say little time to digress and look at something else. If it is less strictly laid down, you should be able to ask your TRI/SFI to cover whichever areas you want to look at - after all they are there for your benefit, and not vice versa. (sometimes they need reminding!)
