whatsercurl, I think some of your tangle issues could be frequency of haircut. We have similar hair attributes, but I get my hair cut every six weeks--and never tangle unless I use a product with mineral or castor oil. I don't care about slip or "grab," it makes no difference in how my hair looks or feels.
