It looks like I'm in the minority; for Intarsia work I use #7, soft woods or #9, hard woods, reverse tooth blades 90% of the time. I find I can use blades longer without worrying about them breaking if I cut aggressively. My cuts, straight or curved, are more accurate with these blades because they flex less than if I was to use the smaller ones and as stated above, I hardly ever have a blade break before it wears out.
