What have you who are experienced hunting with inline muzzleloaders found to be the best tradeoff of length, range, and weight? 25" MR, 27" PR. 28" V2, 30" LR?

I know that the Accura is made in 25", 27", 28", and 30" barrel lengths. Most of the centerfires I hunt with are about the same length as the 25" barreled MR. Also, I'm not getting any younger, so lighter is better than heavier. But I'm use to accurate, flat shooting guns, so even the slight velocity/point blank range advantage of the 30" barrel long range is enticing. I figure the 30" is good to about 195 yards and the 25" about 25-30 yards less.

I plan to buy a CVA Accura later this year. It will be for deer hunting. Where I hunt there is a variety of terrain. A pipe line right of way where you can see a good 700 yards, a field where you can see maybe 150 yards, and wooded areas where you can't see further than 65 yards. I've taken deer here from 65 yards to 300 yards with my centerfire rifles.
