watched that and have to ask:
why not an inspired geo frame with a longer toptube,maybe even a longer fork to gain height(marino will make it the same headangle),and 120 headtube with a few stackers?thats the only thing i see thats got need for corrections geowise.
i did the same,ordered a frame with 1000/+25/71,5°(pure street frame at this time) and built in a trials fork as i got sick of the high frontend.
now its got 1000/+20/73,5° and rides great for me.
if you go for a maybe 435mm street fork it could be more comfy for you,and cause its custom you can take the headangle into account until its built
