Try lance Ohara or
3prong Hawaii, both are great polespears.

Crist is a great spear as well, it's a thicker diameter and heavier spear, therefore a little slower than the lighter spears as LO, Gat-ku, 3prong Hawaii etc but it packs on hell of a punch. If you want a fast spear with some punch the Lance Ohara hybrid is a great option for the Reef.
I have all of the ones mentioned above plus a few others not mentioned.
Good luck!
