I have a homebrew G5RV, with no balun. That is sort of like what you are doing, just with a 20 foot piece of coax between the feedline and rig. It seems to work real well, at low power or high.
Not sure 88 feet of antenna and 75 feet of open wire line is a good setup. The antenna is to short for 80, to long for 40 meters, and I don't know about the upper bands. You will likely always have a high swr on it, which most baluns don't like. Good open wire line is almost lossless, even at high swr's, but you might get a lot of loss in a balun. I would not do the balun unless you have rf problems at the rig.
