I just finished putting a clear nickel drumworks throw off on my omar hakim snare. I dont know if this is a common thing on most drums but i had to drill a hole (5mm) between the 2 pearl preset holes in the drum in order to make the nickel throwoff fit. The holes on the trowoff are a lot clser than the holes on the drum. Let me know if anyone knows of an adapter that i should have used or if i went about it in the right way.... anyways... it ended up working out fine.
