I suggest you go and look up kayak dealers in your vicinity. Most kayak dealers have something they call "Demo Days". This is where you can demo ride a few different brands of kayaks so you don't make the wrong choice of spending your hard earned money and finding out the perfect brand of kayak isn't perfect and it's the wrong yak.
Many people have many different brands of kayak models. On the Texas Kayak Fisherman kayak site, many more people have Wilderness Systems and Ocean Kayak models of kayak and the Hobies are not well represented. Many of us fish offshore out in the Gulf and we use a paddle for propulsion. Don't get me wrong. The pedal drive kayaks are very easy to get from point A to point B and won't tire you out. However, if the pedal drive breaks down while you're two or more miles offshore, the pedal drive kayaks are difficult to paddle with a conventional paddle because they're wide yaks. You'll need a backup spare paddle to take along with you even if you buy a Hobie pedal drive kayak because of the possibility of something going wrong with the pedal drive.
The link to the TKF index forum for all their forums is listed below. You can read a lot about kayaks there they have at least 22,000 members. If you like the TKF site after some lurking, become a member. The Saltwater forum is a great place to learn about kayaks and the BTB (Beyond The Breakers) forum is the offshore yak fishing forum were we fish for surf run specks, reds, pompano, spanish mackerel and king mackerel. The TKF site is the best place on the entire internet for saltwater kayak fishing in my opinion.
http://www.texaskayakfisherman.com/forum/ I don't own a Hobie. I have a 2004 year model Ocean Kayak "Scupper Pro TW" which OK discontinued a few years ago. However, RTM has copied the SPTW and they call it the "Tempo". The link to it is below. The SPTW and the Tempo are made for small framed people since the seating depth is 7.25 inches and the seat width is 17". If you're a big person, your hip bones won't be able to fit into the seat since your physical body frame is too "wide". This yak is very good for offshore, bays, saltwater flats, saltwater marshes, large rivers and lakes. Fast, stable, easy to paddle, easy to maneuver, light in physical weight at 56 pound so it's easy to load and unload from a vehicle and tracks straight even without a rudder. The link to the Tempo is below so you can see what I paddle.

If you don't have many or any kayak dealers near you or the dealers don't have a Demo Day, consider becoming a member of TKF and make a topic stating where you live and see if any TKF members will let you demo one of their kayaks in the models you like. The best place for this topic is the Saltwater forum which gets tons of posting traffic every day. TKF is has many members all along the Texas coast.
I hope this info helps you out.
