Harry,
A good idea is to purchase a fly from the vendor. If the weather gets rough,a good fitting fly keeps your canvas dry.If the weather is fair,they make a nice awning for shade.The reason I suggested Panther is that they make flys to fit their tents.They put in the chimney holes in the right place,no fitsky ditsky.You'd be surprised what a difference a little airtight stove in your tent can make. Chris built a cool little upright heater for his. I like them close to the ground so your feet don't get so cold. Something else to research,Harry. LOL.
