What is better, the support handle or the T-Bar?

The main difference between the T-Bar and the support handle is the form. The T-Bar has a T form which is used for balance and also high intensity bouncing. The curved support handle is made for help with balance and getting on and off the trampoline. 

The advantage of the T-Bar is the speed of removal. It is mounted to the frame making it easier when you want to put the trampoline away. The Support handle is assembled on the legs and if used in combination with fold-up legs, the speed element of tidying the bellicon away after use is lost. 

Both the T-Bar and the support handle can be used on all sizes and models of trampoline. However the support handle doesn't come with a stainless steel option.
