I have the 24 inch Hospitaller and it feels perfectly weighted front to back at 24 inches. I am not sure why you would want to increase the barrel length to only gain 25-50 fps in bullet velocity.
Also, when you start changing the barrel length and the stock, then you are in a full custom build, and the cost jumps sometimes $500 or more. I tried to change some of the things from the other models and my build price was $5,500! My Hospitaller was a compromise and I am glad I went with their pre-custom model. I saved $600 and got all of the features I wanted.
I would recommend that Jewell trigger upgrade. This trigger, installed by the experts at GA Precision, is the best trigger I have ever felt/used.
Good luck and let us know what you finally decide to go with.
