I do like Crowns - a lot! My single Continuum set is also in .25. You will likely be amazed at how accurately the gun shoots with the 380mm barrel, at least out to about 75 yards in my opinion. You may also be surprised at how long the gun gets with the 700mm barrel installed. I actually leave the 700 on my .25 Continuum as it wears a GRS stock and I only shoot that gun off the bench. I also have a .25 which I purchased as a VP model (500mm barrel), since I had extra 480cc CF air tanks and an extra walnut stock. That gun is definitely more handy to carry around and shoot, and is just fine out to the 100 yards I have shot it. More utilitarian and a bit more usable as compared to the GRS 700mm, and just a little more punch as compared to the 380mm barrel.
Carrying the gun around - walk and stalk - the Crown synthetic stock is maybe one of the best. On the bench, however, I find the extra weight of a wood or laminate wood stock to help me steady the gun a little further off a front bipod/rear bag or off 2 bags. And if your hands fit the GRS stock (it seems to me to be sized for fairly large hands), I have never felt more comfortable (and stable) with any other gun stock right out of the box. But I wear size 2XL gloves.
Congrats on your purchase - you did your homework well. It is really tough to beat a Crown with its wide diversity of things it does very well. Some guns may be shorter, some may have more power, others may do this one or another thing better. But as an overall package, the Crown sits at the top of the heap with only a couple other true competitors (which to me really only include the more expensive Daystate Red Wolf, and the less easily adjustable and more bench specific RAW HM1000x).
