FWIW and IMHO and all that...
While you may need a 9/10 weight rod to cast big pike flies you certainly don’t need one to land big pike.
They are ambush predators designed to cover two or three times their body length in one fast lunge to catch their prey.
They are not designed for sustained high speed swimming. They are so bendy that if you give them lots of side strain they always turn around.
I’ve had two in the low twenties on 7 weights when salmon fishing and had them both netted within three or four minutes.
I have yet to hook a pike under 8lb that I needed to give line to, maybe take a step forward and lower the rod a bit but no more than that.
I have yet to hook any pike that put up as much fight as even a 5lb grilse.
I fish on small river/canals where long casts are not required and can see no reason to use a telegraph pole of a rod.
Over to the pike police
