Stu,
Comparing the rods here in the shop, the EP 85/36 has tip stiffness similar to the Ultimo 79H, but the bottom end of the Ripple Fisher is a step heavier.
The extra power of the Ripple is great if you are wanting to fish PE10, but the length of the EP85/36 makes distance casting and working of the lures very easy. The EP82/38 was also a very nice rod to use, it has a touch more power than the 85/36 but won't cast quite as far with the shorter length.
The Coral Viper is stiffer at the tip than the other two rods, it makes a great all-round stickbait/medium popper rod. However, if you are looking for something more dedicated to stickbaiting, then I would look more at the EP or Ultimo. Alternatively, the FCL EXT81MH and Zenaq Fokeeto 83-7 are also worth considering in this class of rod.
Cheers
Duncan
