I used to have a rigid pipe on my Wanner, many years ago I swapped it for a flexible hose to see if it was better. I quickly decided after a couple of greasing that it wasn't, and that the rigid tube was easier to use as you didn't need two hands.
Every since then, every time I grease the front suspension (about every couple of months or so) I think to myself 'I must put the rigid pipe back on'.
I've been doing this for years - so long now in fact that I'm not entirely sure I can remember where I put the rigid pipe. So I guess it's not that big an issue :-)
