You rock!

Alright, I think I got all my answers from that site.  Awesome.  Assuming useful RPM range is 3k-9k,

Stock setup:  1st@3k = 16.1mph,  6th@9k = 128.5mph
14x47 setup:  1st@3k = 14.4mph, 6th@9k = 114.8mph

For me, on the street, 14x47 setup will make much better use of the gear box.  Also, cruising at 65 mph with stock setup I'm looking at 4th gear to be in my happy zone (5k+).  But with 14x47, I can make use of 5th or even 6th gear (nearer to 70mph). 

Also, with the 14x47 setup, I won't need a new chain as the sprocket distance will be shorten by only 0.2" vs. stock setup.  Wonderful. 

I'm happy now.  Once I get over the break-in period, I'll swap out the rear for a 47t.  It's under $70 from ca-cycleworks.  Not that expensive at all.

I understand where you're coming from.... The million-miles-an-hour guys dont get why you'd wanna be able to use all six gears legally.  I thought about the 14t/47t combo a while back.... but let it go due to lack of any useful info on the subject... and now I'm kinda used to my 14t/45t set up...... but..... now you got me thinking about it again....  So, did you make the swap yet and if so, how'd you like it?

couple of things.

I think if you go up in back too much you might have to look at the clearance of the chainguard.

also, not sure about the gearing. i am running 14x45 and according to the speedo i hit 210kph (130mph) today and still had some revs left. i am not sure the error factor of the speedo but i didn't think i would get close to that with the 14/45.

Mostly I just don't want to need to shift so soon from a stop. Perhaps my issue is not the final drive, but that first gear's ratio is not close enough to second gear's (feels like I'm needing to rev too high in first before I will end up at an adequate RPM in second). And it's almost hard to tell the difference between first gear and neutral with stock gearing!

That is exactly how I'm rationalizing it.  I'm not sure why I'm being told that I can only use 3-4.   

I'm waiting for the break-in to be over with.  Stupid rain past 10 day or so sorta put a stop on things.  Haha.  It's sunny today and I rode in, so I should be able to finish off the break-in either today or tomorrow.  I'm having a hard time finding 47T sprocket however. Interestingly.  CA-Cyclework only have 46 or 48 in steel.  There's a version of 47 in aluminum, but they recommend against that.  There's a DP part for it w/ 47T, but it's around $100 w/ shipping.  I'm undecided which to go with.  Really like the ones from ca-cyclework tho, it's just more bling.

Is that Supersprox item available with a plain aluminium centre rather than gold??

No clue, you can contact CA cycleworks to find out.  They are awesome at responding.  Good question tho.  I haven't seen any pics w/ other colors.
