Given your weight, I'd go with the 140 over the 145. You might even prefer the 135. I'm 5'9", 160, and prefer the 135 because it's not as wide as the 140.
If there's a WS dealer nearby, try to demo the Tempest 165 and 170 as well as the Tsunamis.
I'm not as familiar with the current Perception boats.
Demo or at least "test-sit" as many boats as you can. If you want to develop boat handling skills, you don't want to be sliding around in the cockpit.
There are a *lot* of new & used boats that might work for you. Despite your height, I'd stay away from "larger paddler" boats -- they'll have too much volume for your weight unless you're planning on carrying a lot of gear.
