There are probably 4 rods under discussion here?
Kaiser El Toro 150
Kaiser El Toro 180
NS Black Hole Cape Cod Super Popping Special (graphite) and the same rod in the nano version.
I own the Kaiser El Toro 150 and have used the 180, and used the Black Hole graphite version a fair bit, but the nano hardly at all as it is too soft for GTs.
If you want a heavy chugger rod then the El Toro 180 would be the one. It is genuine PE10-12 rod I think as as Chris states. The El Toro 150 is a good choice as a PE8 rod for chuggers up to about 160/170 grams. Neither rod is especially forgiving and you would need to be sure you could physically handle them.
The NS Black Hole Cape Cod Super Popping Special 8.0 (graphite) is a nice all round popping rod, and I mentioned before that it is possibly the best sub-$500 rod of its type I have used. It would not be suitable for heavy chuggers though. Here is a video showing that rod in field action on a very large GT. Lure was a Cubera 150 I seem to remember.
