I always hesitate recommending someone with a 170+ to retake. Plus you have a high GPA. In my opinion retaking might be a waste of time. Check lsn

Unless you scored several points below your PT median, I wouldn’t. Focus on making a strong coherent app.
Soft is eh, especially for YS. I think you have a decent shot, but your gpa is below median and median lsat. Honestly, I would suggest you attempt to get over a 174. You would likely be looking at H, maybe S. Y is a total crapshoot. The extra 2 points from a 173 and a 175 could make a huge difference.
