I've been using BD 16" notched rim blades but they both, IMO and that of others, had defects that caused a portion of the "teeth" to break off. I have a replacement segmented blade but haven't installed it yet.
What are the pros and cons of both? I do a fairly substantial amount of slabbing so I need something that will last longer than the 2-4 months my first two blades did. I guess I should also add that the segmented blade I have is also BD. I guess I'm a glutton for punishment.

I'm using a 16" BD 303S, and have had no problems with it. My blade is about 2 years old now, and I haven't even had to "sharpen" it yet. I wonder if maybe BD had a bad batch of blades, or changed their manufacturing standards ?

I may be wrong on this but the guys at Barranca told me the notched rim blades are to some extent reparable ( they can be peened out) while any kind of continuous rim, including segmented are not. I only run ten inch blades but with constant sharpening, the continuous rim blades seem to work fairly well. According to John of Johns Gems, the MK 301 notched high diamond content blades are a bit more aggressive on had materials like pet wood. I have one but have not tried it yet.....Mel

If you keep trashing notched blades, it may be time to try a sintered rim blade. I've got them on my 20 inch, and knock on wood, no problems unless I screw up locking down the rock in the vice. With a $400 blade, you only do that once, then you get very careful Just my 2 cents. In my smaller saws, (14, 10 and 6) I use the notched rim Gold blades from Covington. again, knock on wood, no problems with the blades. very aggressive,we cut mostly petrified wood and agates and are very happy with the blade life/cost.

the 301 is sintered. I think the recommendation is to try cripmed, which is not the same thing as notched.
