I've got a yx150 with a oko 26mm flatslide and it pulls hard you'll defiantly feel the difference and the stock jets in the oko from dhz work perfectly.
Although I reckon and this is from experience save mate save that little bit extra and get the 160ho you won't regret it and you won't be thinking later, I wonder what the difference is from a 150 to 160. You'll always want more but best to aim high then wish you did.
