I have recently switched to jell batteries and the difference is huge. Much lighter, hold a charge way better (and charge up better and faster). It will cost 3x a regular deep cycle battery but it's worth it if you can afford it. Costco will be your best price I believe - $140 - ouch! But like I said, worth it. I pulled my trolling motor battery out after sitting for 6 months - it's still 90% charged.
