I have a marvel pearl and a SonIQ both drill exactly the same butfor what ever reason the soniq is just a total bust..I mainly throw a down and in shot 15 mph and a rev rate of 300 and axis tilt of 12 degrees..I can throw the marvel between the second and third arrow and it nails the pocket,the same throw with the soniq and usually cant make it to the pocket leaving me with a nasty split..Also it sounds crazy but even when it dose hit the pocket it just dose not sound right..Is it the hd core or is it the r2s cover?I know the marvel is r2sx and the soniq is r2s..I throw the hy-road 80% of the time in a 40 foot house shot and was hoping the soniq would help me out on warn down lanes but as of now it is a total let down..
