Kingstaken, if you are wanting to stay at 150 grains it's the Interceptor, but the dimensions are the same as the Safari being a bit longer. They all fly well, much better than you'd expect for a 2 blade of such cutting width.
We have two Tiger Sharks, which are identical except the 150 Solids have no vents as you surmised. The 135 on the site has the vents as pictured. The Safari's come in at 165 grains. They are the Solid version of the Interceptor, no vents on those either.
The 150 Solids Tiger Sharks have been hard to get ever since Dave introduced them, supply has not kept up with demand. I expect Dave will crank out a bunch more later this year.
