A few years ago, I rebuilt Reaper's forks, as the fork seals were leaking. Replaced all the seals, bushings, etc... at the same time I installed a set of Progressive springs, and went with SE heavy fork oil. It really was a night and day difference. The dive factor on hard braking alone was very noticeable! Bang for the buck wise, it's a no-brainer. VAST improvement! 
Cheers!

I have them and they stopped the dive on braking. I used Aimsoil shock therapy 10wt oil and all is fine there.
If I remember the instructions right they said to stick with the stock oil weight.. I'm 210lbs..

I have the progressive heavy duty springs in my Heritage and the difference is almost night and day. I feel that the handling is better and considerably less nose dive when braking. I wish that I would have installed these a long time ago.

I should have also mentioned that I ride 2 up with bags ful 99% of the time. And you know how them women are (the bags are full to the brim with her stuff and tour pack full of tools with mine. So effectively I’m a 375 pounder going down the road
Anyone ever switch to these? Just ordered them yesterday. Figured my 42k springs wouldnt mind getting trashed either way.
Also switching to 15w oil.
Had and to replace fork seals so cant leave junk alone I guess

You did good. See Report on front Suspension HERE.
The only other low cost improvement would be the Intiminators, which you can see HERE. They make a significant improvement for relatively low cost.
After that, the next step up in improvement gets quite costly. See Report above.

I think you guys are brain washed by progressive I called them when I did the front springs on my 2010 ultra at 250 lbs they told me the only thing they had for me was the heavy duty spring and that was questionable so I looke further and found patriot spring had a series that was a double progressive and they work great
