What is the least problematic, most RAM with Sense 6.5 ROM ?

[Amamba]

I am looking for a custom WM6.5 ROM for Sprint TP2 with minimum problems (zero sounds really good) and maximum program memory available when running Sense.

I am currently on stock ROM with Sense and Co0kie Home Tab and I am getting around 50-60MB free after reset (also load QuickMenu and PocketController but they are small). Tried SPB MS with MobileSense but it gets laggy after a while, even though there's more available memory (probably just doesn't preload stuff the way Sense does). Also not as touch-responsive, seems to have hard time sometimes figuring out if it's a tap or a slide.

So, which ROM should I try and what are known ohshits if any ?
