Should I go for a carver without tip and tail rocker though right? Or perhaps it's better to put it as - it's not a carver if it has tip and tail rocker? Correct me if I'm wrong, but that was the impression I was getting.
I found this simple explanation. A lot of the skis you're looking at probably have some tip rocker to help with turn initiation.
Full Camber (or “Traditional Camber”)
Full camber means the ski maintains a consistent (downward facing) curvature from tip contact point to tail contact point. By utilizing traditional camber throughout the full effective edge length, the ski is able to direct maximum energy down to the snow—meaning the most power, dampness, and edge grip possible.

Tip Rocker (or “Early Rise”)
Tip rocker means the ski’s camber ends before the tip, thus bringing the contact point farther back on the ski. Tip rocker is used to make turn initiation easier (the ski feels shorter and easier to turn), and reduce tip grab in soft or mixed snow conditions by keeping the front of the ski up and out of the snow.

Tip and Tail Rocker (or “All-Mountain Rocker”)
Tip and tail rocker means the ski’s camber ends early at both the front and back of the ski. This allows for easier in and out of the turn, enhances floatation in soft snow, and makes it easier to pivot or steer the ski in soft snow.

Full Rocker (or “Reverse Camber”)
Full Rocker means the ski has no camber at any point along its length. This is used primarily in powder skis as a way to enhance floatation. It is done at the cost of hardpack stability and rebound.
