As clusters go, this is not the most fun. If you were to rate clusters as:
A=Very easy to break out and control
B=Very easy to break out, possibility of not getting a shot
B=Very likely to get a shot, possibility of not sufficiently breaking open cluster
C=Possibly not break open cluster or get a shot
D=Unlikely to get a shot or unlikely to break out cluster
This would definitely fall under B. The more of an effort you place on breaking this out, the less likely you are to get a shot. With that said, there is a reasonable chance you will be successful. What's more, the more experienced players can assure they are not left safe (which is what most posts have shown are people's biggest concern).
Personally, I see too much to gain with going for the run. Although there are bad leaves, it would be unlikely that you will be left with no options at all. If you fail to efficiently break open the cluster, there will be safeties left to play. The only thing you have to be concerned about is safing yourself.
