Can anyone comment on the visual difference between the Talica 20ii/25ii Regular and CAM models? I've looked at a few on the various virtual marketplaces & can't really tell a difference if the seller doesn't have the box. The specs listed online show the regular model has an extra bearing and 1 lb of extra drag, so I do prefer the regular model for flatfalling if I can be picky. If anyone wants to correct that line of thought feel free; I know specs can be misleading when compared to experience. Thanks in advance everyone, much appreciated.
