IMHO you really can't do better than the 150MLX. It "warms up" the "to some" AT brightness and has an overall, full, lush but still articulate sound quality. The one downside is the heavy metal body but I think that's also one of the reasons along with the needle profile it tracks so well and sounds so good. Plus it just feels like a quality cart when you handle it and put it on your headshell. I think you'll like it even better if you can get the counter weight closer to the pivot point. Measure the tube opening, go to your local hardware store and look for the heaviest, hex-head bolt (I use a stainless steel) you can find. Wrap it in some electrical tape and slot it in. Doing so allowed me to move the counter weight from where you have it to just behind the pivot. Just my 2c's.
Yes I love the 150MLX and would hate to get something else and not like it. I'll have to look into an extra weight for rear.
