hha sights
 

I have been wanting to go to a single pin sight and I have been looking at the hha line I was wondering if the extra foot of fiber optic that you get in the ol 5000 is worth the extra 30 or 40 bucks or if the ol 3000 will do the trick I know with the 3000 you can't put a light or the lens kit in it but I didn't plan on doing that any way is that only difference between these two sights?
