Welcome Jim
I have a Seagull S6 Slim. They are both great guitars with great necks. Barr chords wont' be too difficult for you on this guitar once you get the technique down.
As Jeff points out there is an "aha" moment. Took me about 15 months or so, maybe a bit less, but all of a sudden things just started making sense. Maybe it will come quicker for you, maybe not. I just spent the last hour with a friend writing a song and whereas my friend can execute instinctively, it takes me some time. So for instance if we came up with the idea to have a walk up from and a G to a C (chords), Scott just does it. I know what he means, but it takes me longer. I have to think about it. We both end up at the same spot, but I am still like the model T to his Ferrari! Its coming though, it will for you as well.
Keep at it and enjoy the journey.
This year the diet is definitely gonna stick!
