I would do option 1 for the following reasons: one the lss2 transducer will give you the downscan that the hdi transducer has and replace it with the 83/200 one to give you a two frequency broadband option. Doing that will make your elite 5x resell for more. And with that money you can either upgrade your touch units cartography to something like the Navionics + with sonarchart or the go free wifi module or just off set some of the upgrad cost.
