the flight control dont look half bad. id hang on to the hevi shot and run it througha .670-.680 choke. they seem to favor a slightly more open choke. for a 3 1/2 inch #6 load of hevi shot at 30 yds i bet youd see atleast double on the target with a diffrent choke. i wanna say i put almost 200 # 6s out of a lighter 3 inch hevi shot load on a 8x 11 paper or something i forget...id stick with the flight controls till you try another choke..they look good..exspecially 4 shot...the numbers of "kill zone hits may look better for the hevi shot...but dont let that fool you...you will not put those same pellets there every time...i go by density...the FC looks nice and dense..
