It's definitely longer and cleaner through the fronts than the 716T. And a little more snappy than the 505T, you can tell that it revs up faster than its predecessor. Both of these balls actually had too much midlane for me at nationals. Made some money at nationals. But I used my 300T and 300a the whole time. Those two balls are great when there isn't much oil in the heads.
If you liked the 505T, you'll like the 503T.
