I think sf looks stretched enough, but true that some sprinters, especially tall ones, get VERY long. so yeah, sf, i could see you a little longer + higher to go for a similar torso position but some elbow bend, but that kind of depends on a lot of personal body stuff plus fit philosophy. without like a full profile rollers shot to give complete info, i'm not seeing any warning signs - nice knee/elbow gap, upper arm isn't vertical, torso is horizontal, long muscular fit that's appropriate for a sprinter of the level you're tryna reach.
is this the same setup as the picture you posted here of carleton pushing you? because it looks different, and you look a lot longer and lower in this pic - and your position looks a lot better here.
