I don’t know if it is applicable in your case, but the tripod has the advantage of flexible location. A typical peak straddling tripod can go anywhere along the peak of the roof so a “sweet spot” can be found for reception (particularly important if there are trees around.)
An eave mount must be installed on an eave, so if the signal is good at any of the eaves, it is great, otherwise it limits location choices.
If you put 3 10’ poles together, make sure they are electrically bonded. A high impedance/resistance joint between them could cause lightening to jump into the house to find an easier path to ground.
Do you have an above ground or below ground electric service? If above ground, where do you plan to mount your antenna relative to the service wires? Following best engineering practices, if you have an above ground electrical service, you would want a 30’ mast to be 60’ from any power lines. (Additionally check applicable laws, some jurisdictions want a 30’ mast to be 30’ or 60’ from the property line.)
