Is it the GM1 or GM carp1?
The GM1 was a silver fish pole, very expensive I think and probably no good for anything other than canals.
The GM carp 1, which is probably what you're referring to as they are what you used to see over here was a good strong pole. I had the GM3, which was the model above and an all-rounder.
I believe the carp 1 was very strong and could take red hydro.
If it was anything like the GM3, it will be a good pole
