Trick Timeline?

I was just wanting to get some input from people and see how long it took them from when they first started wakeboarding up until they could throw 360s, tantrums, backrolls, etc. I just bought a boat this summer and have been tryin to complete w2w jumps and just get used to riding, no tower and a bowrider at that.. I was just curious thats all.. Im in AR so season is from about april to Oct for riding and Im going start riding during the week so i can keep the "feel".... anyway all comments are welcome!!
