take the advice of the peop's that were saying 'even if it is ok u still should do ppl in single' a good option after is: do your imc in the twin with out the twin rating! it'll get u used to the gh of the ac but you'll allready be on the ball as far as basics are concerned. We see to many people running b4 they can walk and making prats of them selves, expensive! top and botom is you need a good learning base, 150, 172 pa38 etc are great to get this base.
