Hi guys. I'd like to ask if anyone of you who owns the dollies is able to help with some tests so that interested parties can know what they need and buy the correct length. Say maybe around 4 different lenses horizontally and vertically on the dolly, running from one end to the other. If this could be done, it'd really be much appreciated. I'm trying to scrimp and save for one. I'm looking to purchase the 2' version (for the portability) around the end of the year or much earlier if I can. If the 3' fits what I require, then I'll have no choice but to bring another support which equals to additional weight. Hopefully somebody replies. And thanks in advance !
