tricks have nothing to do with whether or not somebody sponsors you. there have been like 5 legit articles on the subject, i can link you if you'd like. it's about attitude, involvement, skill level, media output capabilities, where you live, and more. if i recall, you quit the sport not too long ago, and came back. to companies, that shows a lack of commitment. also, with an unlegit record in the past, a company might not want to take the risk of sending you free stuff and having you bail on them. you need to work on building a positive reputation in the community again. also, sponsorship is about attitude. you need to have a positive attitude. if someone is sponsoring, you will get noticed, if your attitude is right. this probably isn't what you want to hear, but it might be what you NEED to hear if you want to get sponsored.
hope this helped.
