Hey guys, I'm a little new to the whole stringing machines and stuff but I own one but I don't really use it that much. Anyway My friend is probably going to upgrade his machine so im looking at things for him. Price range would have to be below 1000. I looked around the the wise head seems like a really good thing to have. I also look at the combinations and it seems like the Eagnas Flex 940 got good review with it. I was wondering if the Combo 910 + the wise head would be a good combo too? Or any recommendations? I def. want something electrical and something that I dont really need to calibrate. Thanks guys.
