I think Scotty's are the best. I use 3 1105's and usally never extend the booms. So I think 30 inch booms are fine usally. But somtimes I troll three at once in the wind or in a heavy current and find that extending the booms can be helpful. Also turning tight requires a good spread. Ive heard you can go to Barrys bait and tackle in Vancouver B.C. and get em for 250 each american. Outdoor Emporium in Seattle had 22 inch electrics for 269 I believe. That was not too long ago. Hope this helps.
