Finally this morning i polished off the 70-293 (on second shot), out of the 4 (270,290,291 and 293) i thought the 290 was 'less difficult'
that the others but 270, 293 and the beast (291) need a fair bit of work. I think this is the correct order to take them in though.
Difficulty..
270.....8
290.....6
291.....9
293.....8
Not sure if this helps anyone but right now i'm off to pub to get
the rounds in....

Thanks to this fourm, users and Admin.
Cheers
