It depends because one of the keys to getting stronger is locating your weak spots and finding a way to bring up that weak spot up. So my question to you is do you have trouble from the midway point to the top of the lift?
Anyhow, you need to try things for yourself and see if it works because everybody responds differently. As for myself I just think about Mel siff; author of Supertraining said in his book in regards to the fact that sometimes you need to utilize unconventional training methods, as well as create a new training device in order to reach new levels of athletic success.
