MIM 60's original version of the strat definitely is a very usable reissue of an original 60s fender mia strat, for which you'll have to pay double. Still there is a noticeable sound difference. You'll have to decide wether you like it better. The MIM comes with nitro finish (nicely done) and a 7.25 neck. All together a compound radius neck is easier to handle, even a 9.5 one is.
But to get the right (60s) sound maybe you should have the right feeling under your finger tips and comfortable does not translate to "right". Chords not only go down well but sound more substantial (subjective of course). Lead guitar playing is a bit (but just a bit) harder (strings are a wee bit higher; so you can do bendings 1,5 - 2 tones) Bottleneck is quite hard to get a grip on because of the neck's greater curvature.
I would not trade this mim original 60s strat. In my opinion it stands it's ground. I did compare it to an american standard (2011) of mine and a 79 rather old strat (wich sounds better than the two of them together) actually the second real guitar I bought 40 years ago.
So if I had the money I certainly would try to get a custom shop 60's reissue. Alas most strats on offer are made to look older (brr!). What's the word now...roadworn ?....relic!
