steph,
First of all you have to make up your mind what is a Specimen Hunter ?
In my book a Specimen Hunter is anyone who sets out to target Big Fish of a paticular Species, thats not to say he does not enjoy catching Small fish or catching a different species while fishing for the target species.
And in my humble opinion the Single Species Groups are part of Specimen Fishing, they just broke away from the General Specimen Hunter Groups to spend more time tagetting one Species.
So to be a Specimen Hunter, firstly you need to have the desire to target a particular species ?
Lets say it's Crucian Carp, you would read up as much as you could about the species, most know about the pure strains and waters like Cemex Summer Pit and Godalmings Marsh farm.
Marsh Farm being a Day Ticket water would be where I headed to start with and my aim would be to catch a Specimen of that species- 3lb ?
From there I would join the Club and concentrate on the their waters for a season or two, until I had achived my own target ( 4lbs ?)
This of course is only an example, but it could apply to any species and it might be that you are so single minded that you never fish for anything else.
Then again, you might choose to fish for a number of species and have a figure in your mind that you want to achive.
The permitations are numerous !!
