Sup air base harness

i think this may be up here already but, do you need any skydiving or base jumping experience to use the harness? and how much does an average base canopy cost for my weight (65kg naked pilot weight) ? because i happen to be on a budget (15year old, only summer job) and Pal how does the harness feel compared to the older versions of acro harness, like the acro 3 and is there extra padding like the Ava sport harness for the more intense tricks?
