Okay, the Splitfire is now completely understood, so you can stop chatting about it.
I still don't understand the Sawtooth or the Ratchet Blast. I owned and used both when I younger and I enjoyed them quite a bit. They were both incredibly powerful from what I remember because they had minimal ARs and big-ass springs.
The sawtooth stock wasn't that great, but it was one of the first nerf guns to have a clip for quick reloading, so back in the day that made it useful. It has a good durable frame so you can mod the heck out of it, and I've seen some crazy stuff done with it.
As for the Rachetblast? That my friend is one of my all time favorite guns. It had a unique cocking mechanism, that allowed you to recock it one handed. Four shots, and if you nested some cpvc or other barrel material inside the original barrels you could get excellent range. It is flexible in application, great for a quick rapid volley, or for aimed shots.
The one thing you never ever wanted to do though, is open it up. I made the mistake and it is by far the most difficult nerf gun to reassemble, ever.
The Secert shot 1 is great because you always have the second shot in the handle, or if you mod it you can have as many as 3 selectable barrels up front. Just a solid pistol all around.
The Secret Shot 2 has a bigger air tank than the SM2K/1500, and with a simple barrel replacement and air release valve plugging, is one of the most powerful pistols nerf has ever come out with. A great hand cannon and fun to play with.
The Sharpshooter 2 fun 2 shots, easy to mod, integrate or do what ever. Again has a nice beefy look making it another great hand cannon.
As for splitfires the only thing I can say is that imaseoulman is chronologically challenged, because these things didn't come out til 2000. But other than that yes they rock, though prone to developing leaks.
