What’s your niche market?

Decided to focus on some specific props this NFL season and have been having success with Tackle+Assist props and RB Receiving props (17% and 18% ROI, +26 units so far). Seems like it’s tough for the books to get the lines right and they are exploitable.

Still trying to find something for NBA and CBB.

Was wondering if anyone likes to focus on specific props when they bet and what those might be for whatever sport.
