Then you'll wonder what 30's would be like and there's only one way to find out! I do favour smaller vents compared to most people it seems. I've been using 30 vents on my 2413cc type-4 for the past year. 32's are maybe a bit more open up the revs (that's 3500-4500 for me ha-ha) but the tuning between idle and mains and the mains themselves under WOT is much easier with the 30's. That's Dellortos though.
