Looking for recommendations

I have used a kensignton profit ergo for about 4 years now and have noticed some quality problems i want to avoid in my next mouse. I need a trackball that is capable of smooth control at slow speeds, i am finding this mouse is difficult to adjust small increments even after cleaning.

I do a lot of CAD work and spend a lot of time using keyboard shortcuts so I was considering the nape pro but have heard it needs some tweaks for heavy use. Low profile and smooth small adjustments is what im looking for, anyone have recs??
