Most sticks made for these techniques seem to have softer tips a stiffer butts. I run a TFO Pro 10ft 5wt. The 5wt allows me to throw indi rigs and use Euro techniques. A 10ft 3wt will handle 18in+ fish but if you decide to throw an indi it will lack some power to get it out there. I would stick to the 4-5wt unless this will be exclusivly for Euro.
The softer rod also fights fish better as the rod flex helps wear out the fish. Better for light tippits as well .
THEY ARE NOT DRY FLY CANNONS.
