I am considering buying some stuff from Spartan and I have some questions. I am considering a bipod, davros, and optics adapter. How stable are binos and a small spotter on the Davros? I would like enough stability to leave my binos/spotter attached for a couple of minutes and have them stay put on a target area. Also, how much of a difference is there between the light duty bino adapter and the heavy duty bino adapter? I will primarily be using 10x42s. Any opinions on Javelin Light vs. the Javelin Pro? I assume attaching a rifle to the Davros on a tripod is more stable than using using a tripod and a Y yoke - am I right about this? Finally, if anyone has gone to this system, any regrets or feedback? Thanks for your input.
