Just watched another review on YouTube this morning. The guy who did the review claimed that there was a lot of vibration on the shot, and you could visibly see that the back wall was very spongy! Now, this is one opinion. I’m sure if the timing was not set properly, it could cause a spongy back wall, as only one draw stop would be contacting the cable. I don’t see how he could be feeling much vibration either, as he had a stabilizer on the bow as well. Here’s the link to the video.
