I personally like F2, using the DLE enhanced is not random enough at the start, it follow more of a pattern. F2 is hard but shows a lot more varied screens right from the start. THe breaker is the drawbridge scene not being there in F2. Since I am running a reproduction Daphne cab now (sold my original years ago) I have put 3 versions of DL in the menu F2, DLE 2.1 and DLE 2.1 Prototype mode, along with Space Ace Enhanced. I am not finding any major differences in feel or look over an original cab with the laser player other than not missing the seek delays or laser player breakdowns. On my last DL I upgraded to a Sony LDP2000 player which I think was my favorite player using a Hitech converter, I also tried a 1450 which I did not like and it even ate a special edition disc that I could not fix.
