This is a fairly common problem fixed blade broadheads often fly low. The striker is a qaulity head and your bow most likely just needs to be adjusted to shoot them. If you wanted to stay with a fixed blade i would try Muzzy's, Slick Trick's or G5's own Montec all three of these shoot very well. The reason you would try all these heads is that they all fly a little different and one may shoot closer to your field points. If you wanted to stay with the striker i would suggest moving your nock point down an 1/16 of an inch at time and deal with your field points shooting a little high. If you want to go to mechanicals i would try G5's Tekan 2, Grim Reaper or HyperShock broadheads.
