Hi Jay,
Attached is a photo of the Rocket lifting a 10kg weight
You can see the rod has a fairly fast action in comparison to the Komodo Dragon and even the Tokara
The rocket has a very crisp and springy tip section and starts to stiffen up around the 3rd guide down from the tip. The Tokara as a comparison starts to stiffen up around the 4th guide down.
The Rocket is definetly a dedicated popper rod. Ideally suited to a more experienced angler with reasonable rod technique that wants to get the most out of their bloopers.
I would say around 12kg is towards the upper limit of this rods lifting capabilities.
Hope this helps,
Cheers
Tom
