Still on this subject, as I've got a set of WO575 on ebay

I'm looking at the brake line.
Has anyone actually tried the install with the standard CUSE line? Are we
sure it's too short? Reason I ask is a few years back, I had the MoCo's "Touring Pullback Handlebars" on my CUI, and the P&Q book says for them that they bring the controls 2" closer to the rider (I hated them, so I hope the WO575 are not like them at all!), and says to use Brake Line Kit 45212-97B. That's what I had, it was long enough. It's actually a FLHR/FLHRC/FLTR part, and here's the important part - it is no longer than the OEM part 43350-96B. BUT - it doesn't give lengths! So, is it 2" longer than the OEM FLHT 43349-96A, or the same length (I always thought that had 17" lower lines, whereas FLHR/FLHRC/FLTR had 16" lower lines!). If it IS 2" longer, does that mean that the part recommended in this thread - 45252-04 - which is 2" longer than the FLHR/FLHRC/FLTR part, is actually 4" longer than the FLHT part, and I need a 4" longer top line than stock?

I'm wondering, therefore:
- Is the stock CUSE line really actually long enough
- If not, can I use 45212-97B as HD say you can for their pullback bars....
