I also purchased a AOKA 28" tripod; it was just a wee bit too short for me to glass comfortably seated- I bought the same Sunway ET01 extension as above and now I'm back in business
I also have a Kramer Designs Granite Peak tripod, for just mid-sized binoculars it does pretty good and at 8.5 oz, nothing comes close to touching it weight wise. I think it will see less action now though with the addition of the AOKA.
I looked at the Wiser head- looks very nice, but fter the bargain price of the AOKA- makes it more difficult to jump on it.
