While i can't be sure (because i've never studied aerodynamics in any official sense) i would believe that choosing a different balloon would indeed effect both.
Example: if you blow up a balloon it naturally forms a sphere because it is trying to hold as much air as possible with as small a surface as possible.
If the balloon were pressurized with no payload, the envelope would be spherical. There is a complete series of envelope shapes that depend on the ratio of payload-to-skin weight and internal pressure. Normally, the internal pressure is zero and the envelope weight is a high percentage of the total balloon weight.

The albuquerque event is the largest hot air balloon festival in the world, with over balloons participating each year.
Spherical bubbles minimize the amount of contact between the inside and outside substances because spheres have the smallest surface area of any shape, for a given volume. If you take a sphere (like a bubble) and a cube (shaped like a box) that have the exact same volume (or can hold the same amount inside them), the sphere will have a much.

Spherical balloons would generally carry the pressure created loads globally in the balloon material. The shells of spherical balloons were fabricated with very precisely cut gores which were joined at their edges with adhesive tape. The process of applying the adhesive tape required precision equal to that of the gore cutting process.

This expression is valid for both real and complex harmonics. The result can be proven analytically, using the properties of the poisson kernel in the unit ball, or geometrically by applying a rotation to the vector y so that it points along the z -axis, and then directly calculating the right-hand side.
1) a hot air balloon stays on the ground (or descends) when the air inside it is too cool. In this case, the weight of the balloon (blue arrow) is greater than the lift (red arrow). 2) when the air inside is a bit hotter, the balloon floats at a steady height because the lift force and weight are now the same.
Hot air balloon physics – operation if the balloon operator wishes to lower the hot air balloon, he can either stop firing the burner, which causes the hot air in the envelope to cool (decreasing the buoyant force), or he opens a small vent at the top of the balloon envelope (via a control line).
