Hi Ed,
I'm sorry, but I can't seem to locate an e-mail from you, but in anycase, thank you very much for the compliments, and even the consideration!
As I have told a few others, my personal favorite is "Little Friends II", if I were to choose just one. It only covers the P-51D-5-NA variant, but within "Little Friends II" you also get two different flight models - one for the 'typical-stock' fillet-less D-5-NA, and another for the filleted D-5-NA, so with this one product, you can 'feel' the difference between the two. (Having said this, you will not find any lesser quality or lesser completeness in Little Friends (I) - they are meant to compliment one-another - though I have been told that Little Friends II is the most 'perfected' of the bunch, but I think that is harder to say, now, with the "Little Friends (I) Redux" that I put up in the file library a couple months back).
Little Friends II is also near-closest to my interests, based on the lines of the D-5, and that fact that so many of the most historical P-51D's were D-5-NA variants. Even if you were to become a connoisseur of the Mustang one day, I can't think of a better product of the four to go after first (though I suspect that perhaps those who may have most of an interest in Iwo Jima based Mustangs, might prefer Little Friends (I) the most, which would be perfeclty fine as well, as it is just a different variant that Little Friends (I) provides - in my view, none of the models/variants in Little Friends II are any better, they are just different types).
(BTW, I don't know how many people I have mentioned it to yet (probably only a few), but there is a plan in action to bring forth texture "reduxes", like I did for "Little Friends I", to both of the Warbirdsim P-51D-restored products as well, so that they will be at the same level as established with both of the "Little Friends" line of products.)
