How does this tripod and head sound? Induro A-113 Alloy 6M Tripod Gitzo Centre Ball Head - 0 Magnesium, G1077M How is the tripod for weight to size? Is it sturdy? Is it durable? Any thing else I should know? As for the head does it stay put well? No shiffting to one side or any thing? Will these 2 work together (I'm pretty sure they will)?
