I got sent a link to a line last week, and i was astounded. How on earth can you have a #2-5 fly line?! There is a simple standard that should be used, and it is rarely followed nowadays with lines getting heavier and heavier.

'Ideal loading point at the tip of the rod'. What do you think about this 'spring theory' still being used?! I believe that the colour change shows you the start of the running line, and the end of the head/back taper. For short headed headed weight forwards, i think you need a significant portion of overhang to cast them a long way, and i don't think the colour change at the rod tip will give you this. I haven't cast one for a while (Lasse maybe you can help?) But maybe with something like a Rio gold, the optimum carry for that line is some where around half way down the running line if i remember correctly. What do you think?
Sorry for the rant

All the best
