PiTBuLL there is so much good, detailed information already on the difference b/n those "lines" & true APBTs. I truly think it would benefit you more to do a search & get to read all the many different responses already then, (if after the 2 weeks of reading

) you still have any questions, feel free to ask. But I do believe all your questions will be answered. Plus, many of the existing threads have good conformational info, differences, & pics as well. Happy hunting!
P.S.-To do your search, just click on the "Search" button (2nd to last in the bar) & type in any of the keywords you mentioned.
