i glued mine to mag floats, i got 2 maxi jet mods 1200's, and just got a seio 2600 for a really good price at thereefstop.com but its to big for mag float. Maxi jets mods are stronger but propellar always changes directions at rubs on stopper to kick it back in right directions, very noisy. so honestly i like them on mag floats so i can slide them around to get right flow.
