If you read the other thread, you know I received my sidekick today. I also ordered the P-30 lens plate that Wimberley recommended on the chart on their site for the Sigma 150-600mm C lens used with a sidekick. I only have a P-20 which I can use for my 50-150mm.

Well, Wimberley included their catalog in the box with the sidekick and on that chart it recommends the P-50 for the 150-600mm C with the sidekick!

I want to be safe and use what I should be using since my best gear is going to be hanging from it but the P-50 seems like more than what I would need. I'm debating whether to return the P-30 when it comes on Friday. Any suggestions on which Wimberley recommendation I should go with? Maybe I should go with the P-40 and call it a day!

I emailed them but have not received a response yet.
