I agree with this. I use 130's (as single tanks, I own two) and the only sense in which you could say "too much air" is that the first couple of dives after switching from an 80, you might find that NDL are real things to be considered.
Based on the tables, and the type of diving that the OP said he was doing he would have to be cutting his air supply real close to get into deco obligations, even with 130cf of gas.
