Even after almost two decades of competitive casting I'm not sure how you quantify "competition grade".
When I started competing back in 98 I used a Lamiglass, then a Breakaway, a Greys (all fishing rods that were used on the field). I then purchased a Zzipplex and after a few years a Century. I went through several AFAW's (really just fishing rods, some very stiff).
As my skill level increased I was able to bend progressively stiffer rods and obtain more distance.
I have observed over the years a recurring theme in fishing rods used on the field for competition. A caster/fisherman sees the top level casters on the field and thinks.... those guys are using XYZ brand super stiff Primo-Excalibur-AAA-TTR-Full Tournament rods so he buys one thinking it is the key to distance, only to become frustrated when his distance actually goes down because he cannot bend the new rod. The fact is, you must have very good technique OR be a very powerful guy (still needs some technique) to ever get the performance potential out of a super stiff 14-15' long tournament rod.
Are Cast Pro Series rods "competition grade"?? In the hands of many guys, my 13' 6-10 or 8-12 will perform on par with or even better than some of the top name tourney rods. The CPS heavers are designed to be plenty powerful to throw heavy weight a long way but still bend enough through the butt section to be easier on the body. What this translates to on the casting field is a rod that will throw 125-150 grams a very long way with a tournament style cast. I can add a 12' extension to the butt for a 14' rod that will give even more range.
It is asking A LOT of any rod to be user friendly while fishing and be a top notch performer for world class casters on the field. I have a wall full of Century and Zzipplex tournament rods that I just don't enjoy fishing at all. Too long, too stiff, and too heavy. I would not relish the thought of fighting a big drum on one of these beasts.
Can the CPS rods be used for fishing and field??
Absolutely.
