I don't think you have triangle head at all. You can get good clumping with either a good leave in conditioner or a curl cream. Recoil will probably help, my Beauty without Cruelty leave in clumps my hair well if I scrunch the product in real wet hair rather than rake. Also scrunching in product with your hair hanging upside down will help clump all the way to the roots.
I bet if you play around with conditioners and curl creams your hair will get curlier. You look like you have a nice strong pattern it's just not corkscrews. You have lovely hair, I'd work with what you have!
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
