Huntin straight pits or 3/4 pits?

the heats probably bout the same but in a long 3 or 4 hour race i dont think a pit can stand the heat like a cur can...i may be wrong but after a dead pit last year that we walked into a bay about a half a mile and caught one litter sow he had a heat stroke thats the only reason y i have my doubts....pits do have a lot of drive, but i think they lack in having bottom and a good nose, and thats the two most important things i look for in a dog...iam not saying you cant catch alot of hogs the way you hunt, its just not my style.
