I bought a JAg35Pro and a Shrigg Rig a few months ago, fact of the matter is I am scared to use them, I know when i shoot with my naked HV20 or have the WA lens on along with auto focus on I am going to get great results. It seems like I can't trust myself to use the Jag35 on important shots that I only get one chance of filming. For instance, last weekend was my annual family camp out, there were over 80 people there and I wanted to shoot a documentary. I setup one cam with the Shrigg/DOF adapter and my other cam with the WA lens. I just couldn't get myself to use the Shrigg/DOF. It was all setup ready to go but I just couldn't get over the fact that I might not like the results, so I played it safe and just shot with the WA lens.
It's nice to be able have all these tools and accessories at my disposal but I learned the hard way they are tools that you need to learn to use and sometimes the learning curve can be tough and should be considered before spending a ton of money on new toys.
