Someting I've noticed (can't help but notice) on our sport league shot is that after about 10 minutes of practice and maybe 4 to 6 frames of game one there seems to be a sudden transition. I have to move about 1 board right with my feet, maybe slightly more, or I can't get the ball to the hole. After many 2-8-10's I'm coming to expect this. Is this sudden carry-down (I assume that's what's going on - the only other thing I can think of is that I'm suddenly gaining speed) typical of a sport shot? Strangely though, this seems to be the only major transition I see in a 3 game set (4 bowlers on a pair). Once in a while I find that I have to move right, then, very late, move back left, but very rarely.
My comment is, very simply put, it doesn't appear that you can score on a sport shot without being very good at spare shooting. And, shooting spares on a sport shot is, if anything, more difficult than throwing strikes. On the THS I rarely chop the 6 off the 10 - on the sport shot I do it frequently. But, while I convert maybe 70% of my 3-10's on the THS, I manage to miss at least that many on the sport shot. And we all know (I hope) that straighter is greater at single pins on a sport condition. On the up side of spare shooting I now know how to try for the 2-8-10 - lots of practice ya know.
