Hi Guys! Thanks for all of the input, advice and tips on how to make to J-45 work for me. I listened to a lot of side by sides and can see that the J-45 is equal to or slightly better than to Martin D18 to my ears. So, that is good, Then, I also listened to D28, HD28, 000-28 and D35 comparisons. I think that I can see the future need to get a Rosewood back and sides guitar to playing the NY style acoustic note runs that I like. Like "Tell Me Why" for example.
So, my plan is to keep the J-45 and have it setup for easier playing. Then, keep my eye out for a used Rosewood model. Unless someone would like to trade me a D28 for for J-45 :-)
