Injector spray pattern

I was looking at some flow matched injectors on Racetronix and the 60lb injectors list cone shape for the spray pattern but the 80lb injectors list pencil type for the spray pattern. Anyone using 80lb injectors having low rpm driveability or idle issues due to poor fuel atomization from the pencil type spray pattern?

Thanks

Mine idles fine once its warmed up. Think I just need to adjust the time it richens the mixture after startup.
 
I would say that it varies and don't worry about it. I've tuned many with different injectors and how much the thing wets during cold start is more a function of port work and camshaft than anything else. On some cars I find that the stock cold start tables are too much fuel and then on the other hand the next one I do will be lean and need more. I think you'll just have to wait and see how yours acts.
