Looking for opinions on which brand of longtail props come with the heaviest cup from the factory. The backwaterinc props are great for the price but I find they lack cup for running through thick mud. They tend to just spin for a while before biting. I'm running a 9x8 backwaterinc prop on my 35 swomp now. Thinking of dropping. Down to 9x7 with heavy cupping to get more bite in the mud but keep as much top end as possible.
