Riggers and rod holders mounted to the plywood. Riggers have a 6X6 3/8 thick aluminum backing plate under the plywood Dipsy rod holders I used SS fender washers as a backing. Rigger booms are extended to 5ft when in use with 12 lb weights. I usually run the riggers 90 deg out to the sides.Everything is plenty strong enough and been there a long time with no issues. Good luck with whatever you decide.
I built a couple pedestals out of aluminum and mounted them to the plywood seat tops where you have your rod holders on my little boat. Will post pictures when I get home
My buddy went 4 for 6 this morning in 5 to 10 fow casting plugs and spoons from his drift boat. The fish are there but it;s a tough bite.. Good luck and post a report when you fish.
Happy with my Tekotas and I own over 2 dozen between 800's, 600's and 500's. Taken an awful lot of fish on them and no regrets. Good luck with your decision.
If you decide to go with scottys I would recommend the older style with the mechanical counters. Pretty much bullet proof. Also the extendable boom and the swivel base gives you all the flexibility you will ever need

Usually doesn't matter to the fish. It's more of a speed thing dependent on what you have in the water and how you adjust your boat speed to the current. Plenty of days working the same area I have been taking more shots going in one direction while another boat in the area is getting bit more moving in the opposite direction.
I put a couple hundred ft of 40 lb mono on the 600's and 1000 ft of 30 lb 7 strand fills the reel nice.Edit. Good luck.
Opps sorry. you were asking about the rigger reels.
