Spriggan Requiem spin direction

hi I have Spriggan Requiem I just have a question on which spin side it is competitive? Is it right or left? or it depends on the opponent? And can you please explain why it is the most competitive spin side.
Left spin is more competitive in a defense combo because due to it having metal and rubber it can be used as a spin equalizer to other right spin beys
If your opponent's beyblade is in LEFT SPIN ( eg : Nightmare Longinus ,Bloody Longinus,Lost Longinus, etc ( and the only exception is Drain Fafnir ) ) , Spriggan Requiem should be in RIGHT SPIN mode , and if your opponent's beyblade is in RIGHT SPIN ( eg : God Valtriyek , Seig Xcalibur , etc ) , Spriggan Requiem should be in LEFT SPIN mode , but for Drain fafnir ( which is in LEFT SPIN ) , Spriggan Requiem should be in LEFT SPIN , too ( because they both cannot spin steal , anymore )
