I'm sorry chap but I wouldn't call that carp a linear,not even a half linear as there are only a few scales on the lateral line towards the wrist of the tail.What you have there looks to me like a typical sparsely scaled Simmo fish.(stand to be corrected)
Linears are my favourite type of carp and you can't beat a perfect zip linear with the right colours.
Although not my biggest fish this ones one of my favourites..
