My Vamo is going strong, but that is prolly because I only use it to rebuild, but I did use it to vape with my kayfun for a little bit last week, and it was a good vape. I never had any problems with my APV's performance, it was a really a size issue that made me toss it to the side. Even in 350 mode the Vamo is very big
It wouldn't surprise me if one day I got a pipe mod, and I actually kind of like the hammer ... it may be good to have one because just as you said about the kayfun Mini, I think the Taifun GS might look better placed on a pipe. I like the GS, but it looks strange on mechs, so I don't use it at all.
Love the Hammer in 350 mode. It's my number one vape with a kayfun right now. The only problem I've had with it is if you try to subohm too low the spring in the 510 will get hot and collapse. I'm sure they did that on purpose for safety though.
