I chime in for you, 6'4", 235, 35 inseam,size 15 boot, just purchased a Russell Day Long seat system.
Great improvement over stock, like day and night,with leather option and built in back rest fully adjustable.
Pricey for some, but priceless in comfort.Drove 720 mile one way to get fitted and it was well worth it.
Went to San Diego to DHS and had him (Dan Sherbourne) install for me one of his custom shifter linkage, which provides you with a noticeable shorter and crisper shifting(removes the slop) and raised the height of the shifter measured from the ground to bottom of shifter at 11" to 12".
There is a possibility to do more in the raising of shifter height, but for now I'm going to try this out.
That and a 20" Madstad shield, when it get here I expect that to cure my noise issue, I had a 15" Madstad shield but it was not to conducive for my height and needs.
Might consider the drop down pegs as a experiment in the future, but hate to give up ground clearance, twisty person.
Hope this helps in your quest.
