Having worked on many boats with tops and towers., I will give you my opinion. Take it for what you will.
Firstly (and foremost) the t-top or tower needs to have a great deal of support. Double the thickness of the regular deck area, and thru bolt. The top should have a MINIMUM of 2-4 connections to the console for additional support. Be careful to consider pull tubes for mounting additional electronic devices like an anchor light (required), spreader lights, and antenna mounts plus the cable pulls required for all of the above. If at all possible, pull all cables for any and all options you want to put on the T-TOP before you intsall it. Ther are MANY applications where the tubes are welded too close with too small of holes between the pipes where I cannot drag wire. It may seem like a minor issue now, but it becomes a big issue when you want to keep a clean install going and mount things.
