mas maganda ang flat sa performance pero mas madali itono ang round...pero tulad ng sabi ng ilan na walang mahirap na itonong carb sa isang magaling na mekaniko( kahit pa yung notorious na oko carb he he he)

Flat slide carbs are made for two stroke engines and round slides are for four stokes. It's hard to set the flat slides because it's not made specifically for four strokes. I had a big headache with my OKO 28mm flatslide carb and thats the reason why I sold it and changed to Keihin 28mm round slide carb.

both are good carbs, it will depend on how you will able to tune it properly

just prepare many pilot jets and main jets

I agree, but on my case I tried many jetting combiz. 38-120, 38-125 40-125, 40-125, 41-125, 41-130, 41-120 etc. all of these combiz gave me a top speed of 120kmh before it drops. Maybe I just had a lemon. Anyway, since I changed to Keihin round slide I got far batter top speed and idle consistency.
