New to me bow! need arrow help please

[ductape]

I bought a Hoyt Scout recurve today 64" 51# @28. Its a little worn but nice. My question is what arrows would fly best? I took it out and shot it with my arrows from my long bow ( thunderstick II 62" 60# @ 28 ) and they seem to fly sideway to target. They are carbon Beman 400's ics hunters cut to 30" with 200 grn up front. Any input would be great!!! Thanks
