How high are people taking Speed on STOP players?

I like 155-160 on two players who can serve as the gunners on punt coverage and OU2 / OU5 on kickoffs, but aside from that you can stop around 140.

150+ speed combined with 15 special teamer can really shut down punts and cause lots of fair catches. On kickoffs it usually results in a slowdown waiting for the KR to field the ball. So if you go higher than 140 you need to be able to accelerate fast. imo
