Hmmm
Hmmmm
First !!! U need a need Freak Barrel with .684 insert !!! it won't make u disapointed !! trust me. it would be nice if u get the whole set but u won't use it all really, its kindda wasted money.
Second !! u do elec hooper Man !!!! don't be stupid !! no men stupid enough to shake them hopper every mins unless they ran out of battery in the game !!! (Happen to me once) 
Get Halo it is great, it won't make u cry but if u can get RaF of ur gun about 8 bps then don't give a **** to Halo unlees u got IR3 angel or them amazing marker out there !!! Get Richochet, its cool with Lcd screen, ball counter and timer with sound. its look so cool man !!!! it feed about 10-12 bps not bad not bad
Thrid !!! U don't need to man !!! all u need is defferent type of spring hard, soft, middle coz it will effect on ur bolt. ohh !! also the volcity !!! sometime it is annoying becoz the bolt has very sharp end inside if u look, this is make the ball damage before the gas push it out and then to the barrel. if u got good barrel and low preesure u will be fine!!! Trust me mate !!!
