Livescope vs mega live for trout trolling?

I have a helix 7 already, so was looking at the mega live, but most consensus seems to be that the livescope is better, especially for trolling.. I’m often fishing up to 30’ down and 120’ back and want to see my lures with whatever I get. Would that he too far for the mega live to see? Would that LVS34 work? The LVS62 seems a bit overkill..
