None, it's just a mental block cuz the thing's so expensive. I see a ball go half long, I more often than not hesitate and half ass my attack.Curious, how many rubbers have you broken attacking half long balls? Chipping the edge of the racket is very normal and is hobby hazard, but over time, you just accept that some balls you can't attack and you are okay with losing the point or pushing. But if you have broken a lot, then sure, get something cheaper but I don't think this is the kind of thing that should be influencing what rubber you choose to play with. And as an aside, I think looping half long balls is easier with tacky rubber but that is not important here.
