Replying to Tramp help

well i posted a vid and everyone says jump higher.....im jumping comfortably, not really pushing to go as high as i can on my tramp and thts all i can really do, my tramp feels loose i spose but its brand new (circular 14 footer) is it just too loose? cuz i can jusmp hihger but theres no control in it if i do. should i cross my springs? its new, i tried earlier and it kinda started pulling at the hook things that are attached to the mat where you hook up the springs. my tramp doesnt have the gromets put right in the mat. will it do any damage if those hooks are pulled all sideways??
