Pinto x TB works depending on the TB you use.
Wine Reds, BKK, or Shadow King Kongs make for lowest possible outcome of pintos. For max number of Pintos use Black Pinto x BB or Red Pinto x Red Bolt. Tested this with 5 Wine Red females with 1 male Red Pinto and 5 Shadow females with 1 Black Pinto. Results were 5% Pintos at best, but using the other combination I mentioned I got 60-70% Pintos.
