Hi Norbert,
I use CTS blanks, just email CTS with the model number to get the factory specs.. I believe you are referring to the 25-40kg blank which has a suggested cast wait of 250gm. It is a powerful rod, a little for firm for most applications...I really like the 150 and the 200 - PE6-PE8. All of their blanks have a parabolic action - including the jigging blanks, some fast taper also. Very strong and relatively light in weight.
The 150 will cast 120-180 nicely, the 200 has a bit more boogie so will cast 180-220/230 really well..I also have the 100 which is a great light option with plenty of power
