Hey, Not raggin on the other S2 594's, as I have fondled the Pattern Vintage neck carve (for a few minutes, in the Local GC) ...
BUT ... If you are diggin' on the Thinline, the other two are radically different ...
The SC /DC are heavier guitars (but by no means a problem, Heck, I like my Two Ton Tele TE-52 by Harley Benton !)
But like said here ...
If you love that neck, then maybe another Thinline. Keep in mind the DC and SC are going to have the Pattern Vintage neck profile.
The Pattern Vintage Is probably the chunkiest PRS neck carve available ...And then it does the "asymmetry thing" ...
Which in time I might like ... But I cannot spend $2K on an "experiment", especially when I already know , The Thinline is just about perfect for me (if only I could get that flamey/stripey veneer top !)
Or Heck ... P 90's !
The 58/15S pickups appear to perform "differently" in the beefier guitar (people don't seem to like them as much in the heavier guitar, where Thinline and SE Hollowbody folk dig 'em ...
So Thinline is the one for me, even though I already have one... I like the idea of a "backup"
