Thats what I call a catch a fisherman rig. A rig like that goes against what I know about topwater fishing. Specially rigged rigged with frogs. Maybe more successful if rigged with poppers on a lake with shad or herring, but not something I would recommend.
Topwater strikes are low % to begin with. Do not give the fish options. Make the fish zero in on one target on the surface.
The frog rig is set up for three frogs. You can only use two baits at one time in Mass.. You would need to remove one frog or at least the hooks on one frog...
Ive always wondered on the laws with A-rigs but when i had asked a game warden he said as long as its one rig together then its legal. He compared it to Jerkbaits with 3 treble hooks. But id love to see what others have to say about it.
