Hi, I've read through some of the old threads here and found no real cons for either the Wimberley Sidekick or the Jobu Junior. Both are highly regarded and have their own features. I have a Markins M10 and like this ballhead but I have been shooting a friend's camera (D300 + 500/4) with a full Wimberley and really liked this. So I'm looking for something similar but I'm shooting with "only" a 70-200VR or 300/4 with or without a TC and a D200 on a Velbon Sherpa Pro CF-640 tripod. So my needs aren't that great. As exchange is a little difficult here in the Netherlands I want to buy the correct item: either the Sidekick or the Jobu Jr. 2 with the additional L-plate for bottom mounting. Price is about the same and also weight is similar. The only advantage I see for the Sidekick is the quick change between Sidekick and ballhead. Any suggestions?
