Rapala has them listed as 7/8oz.

I use Norman's mostly but I think I see a pattern from what people are saying

DON'T SLAP THE RAPALAS ON THE WATER OR FISH THEM NEXT TO ROCKS

you do that and they won't break

just my two cents

Rapala makes fine cranks.  As far as not consistently hitting 20 feet, there are not many that do.  DD22 will only reach about 17 with the right conditions.  I fish DD22 mainly, but that is because they are quite a bit cheaper  

I have used the DTs religiously for two years. I broke my first one slapping the weeds off and have not broken one since because I stopped that. I figure about 50 real hours of use. I have caught many many bass on these, including an 8lb with no problems. I prefer the DT 10 which I can get down to near 20' holding my rod tip in the water. I have used the new DT 20s and can get them down to at least 25 feet using the same method. However, my DT 20s came with Sure Set VMC hooks and I believe they are much more likely to grab weeds and hold on to those weeds due to the level below the lure to which the hooks extend. I am going to replace the VMC hooks with smaller regular hooks from a DT 16 and I'm sure they will serve me better. They have become my go to crank.
