The 99s are 9'9" 90% of my fishing is done with either a 4100 or 6100 Z-axis, both 10' rods. I have a 99 and have used it. The 10's benefits far outway the extra foot in the bush, actually it's really a none concern to me it's only 11% longer then a 9. plus packed it is only 3"s longer then a 9. If you want to easily be able to make bombs, high stick, "sit in a float tube" or single hand spey the 10' really has it's benefits. 163 days of my fishing this year were spent in the bush, with 10's
