I agree with pookie's comments on single vs. dual arm. I've tried out the sportster once and was not pleased. With that option out the door, I'm looking to spend about 2 grand on a stabilizer system (vest, single or double arm, and sled) and wanted to get someone's opinion on what system would fit simple walking shots. I'm now looking at the Smooth Shooter or the Indicam. Its a toss up at this point. Any suggestions or other models you guys have in mind for about 2 grand or less? Any feedback would be greatly appreciated.
