Just to clarify, nobody uses Alveys in international casting competitions.
The smart folks at Alvey created a "new" casting weight category that did not exist before [about 2 ounces], and declared themselves the new record holder for that category.
Official competitions [using metric sizes of course] use about 4.25 ounces [junior], 5.25 ounces [ladies], 6.25 ounces [mens].
In some practical fihsing applications, no doubt the Alvey would be tops.
I also hung out a lot at Hermosa Tackle Box back in the day, and especially remember Jerry Morris trekking up to Morro Bay and absolutely slamming the big albacore [and occasional opah] on the Alveys.
All of that said, virtually 100-percent of international competitors use either the "European version" of the Penn 525MAG [much more elaborate mag system], or the highly-customized casting special versions of the Abu 6500 called "Blue Yonder" or "Chrome Rocket".
Although the distance record is a moving target, and I don't follow the circuit closely, it is well over 900 feet [yes, 300 yards!!], and I think the current record holder used a highly modified Penn.
Another funny thing about the whole casting thing, the Europeans totally dominate, and even the best Americans are not on their level.
My theory is that fishing in Europe is mostly pretty poor, so casting itself evolved into a sport of its own.
Here in the US, where fishing is usually pretty good, we spend our time concentrating on catching fish!
