oh, my bad. 
the combo’s are super crisp!
I think its just lighting in some of the clips. like the one at 3:45 - 3:55 looks really nice and clear and you can see everything that is going on. but some of the clips are darker and blurry. I had to say something bad or your head might blow up man
P.S. About the CF base - Mine also stripped out the squares so i just have regular bolts with nuts on them and you just hold them from the top and tighten them. works really well. mine are allen key head ones too so they dont cut hands
