I just bought a kickport the other day. Unfortunately, I am receiving it as a Christmas gift, so I have yet to try it, however I have heard amazing things about it. I have come across one review stating that it does not deliver, whereas every other one says it does what it claims.
I tried porting the last reso head I had. I heated a 5" can and melted the hole. It worked relatively well, but after about 5 minutes of playing, the head broke around the hole. I think this was due to the fact that the head was pretty old, but I dunno.
I think as long as you follow the directions included with the product, your head will be fine. Also, there is some kind of securing design to prevent it from rattling or anything.
As for Los Cabos, sticks are sticks. Sure, everyone is partial to one brand, but you can't really compare stick companies like you can drum or cymbal companies. When you get down to it,
Promark and
Vic Firth are basically the same, as is
Vater and
Regal Tip and every other brand out there. Some of them have wider selection of woods or tip shapes/tapers/sizes/etc. or come out with stuff like hot-rods or a new type of brush, but wood is wood and almost every hickory stick lasts about the same amount of time. Some companies brag about how their sticks are weighted and matched, who cares? As long as there isn't a huge difference, I doubt it will affect my playing. I don't care what I hit my drums with as long as it doesn't break and feels good enough.
