Seems you've gotten a lot of response about the foolishness of rushing a straight shave; kamisori or otherwise, but reading your original post it seems to me you're really looking for a good Par time.

My shave total time takes 17min or less from beginning to lather to walking out of the bathroom. That's at a healthy relaxed pace; getting ready for work in the morning. I can do the same shave with a DE in 7min; so if I'm in a hurry that's what I go for. That's shortening up lather time, no strop time (2min), less care and caution on account of the DE. Could you do it faster, certainly...some guys can hit eagles and birdies regardless of par. Lots of factors go into that though.

I've never shaved with a kamisori, but I've got 5yrs of daily shaves with a straightE 9:1 respectively. A properly setup DOVO should not feel floppy. I've used razors where the scales were loose...it's not enjoyable. I'd encourage you to get that remedied.

Peace,
Jim
