Not sure which "lite" model you are talking about, as they offer a couple.
I had a Taurus 85 stainless, which I liked. Currently have a 605 Hammerless (CIA) blued, and a Taurus 425 Tracker in Stainless steel.
I have been happy with them all, but...
Every one of them has been in need of tweeking. The internals on every one has been rough enough out of the box that the trigger would get stuck in the "pulled" position and refuse to reset.
Popping the side plate and polishing the internals made them all function fine and gave them nice triggers. Not a big deal to me, because I would have popped the side plate and cleaned and inspected them anyway, but it was sort of required with these.
In all fairness, 500 rounds at the range would have done the same thing. Some people would have freaked and sent them in for service work. Others would have just shot them untill they were broken in. I buffed them up a little and lubed them good.
The other thought I have is regarding the grips and the hammer. A pocket gun with a bobbed hammer or internal hammer and wood grips would be a little easier to draw, would it not?
I see Taurus offers Rosewood grips. They would be better on my 605 then the rubber grips. For $35.00 I may just order a set.
Sorry none of this actually answers your questions. Just rambling.
