110x12 is a good set, but I would contend that you aren't doing the exercise correctly. However, that is a very argued point on bb boards.
The first thing that I would tweak is where you are pulling the weight to. You are using a straight up and down motion, which isn't all that bad except that it isn't an effective plane of motion if you are trying to work your lats. It hits your upper and middle back. Now if thats your goal then don't change. However, if you are trying to have the focus on your lats you should pull the weight into your hips. This is the form that was used by Lee Haney and he would rarely use more than 75-80 lbs.
The second thing you are doing is exaggerating your range of motion. Instead of keeping your spine stationary you are rotating at the bottom and the top. While this may allow you to use more weight, it takes stress away from the target muscles and puts it in your core. Also, it puts a lot of torsional stress on your back. Basically in the video, you're using muscles on your left side to help aide the right side when does muscle should be stablizing only. This rotation can be dangerous and lead to hemorrhaged discs and sciatica. You need to perform the rows without any rotation and focus on having just that one side do the work.
Here's a good vid:

The only difference I would make is pulling the weight to the hip bone instead of straight up.
