Welcome to the Forum! And welcome to the addiction of Jeep! Most people want you to post questions in the model of your Jeep section. You have a JK it should be in JK tech section.
I have an '04 TJ when it HAD a full soft top it was very easy to drop and raise the top.
Purchased a '12 JK for HER in Dec. Dropped the top on it a week or so ago. IMO compared to the '04 it is a PIA, putting up and down. It is not near as easy. I did find that standing on the back bumper to get the header started over the roll bar made things much easier.
I do like the sunrider feature on the JK but right now, for me.....I will be happier in my TJ....as far as top less and ease of use go.
