The first time I heard Jafa's Merlin I thought that is it,that is dam well it!!!,the sim for me,personally came alive on that day,I have never forgotten that.
Whilst I can't deny the devs have done an outstanding job on the sounds,and I love the new 109 sounds,they are just superb,for me Jafa's Merlin still reigns supreme,those flybys,oh man,just incredible.
