My son had been a member at sponsorhouse since they started and this year dropped his membership.
Despite having 3 great seasons as far as results the past 3 years he has not been able to attract any good sponsors there. The majority of people signed with sponsors from there will be required to buy merchandise they often do not need at prices that are not any better then you can get on line or often at the local shop if you get to know the owners. There are a couple good deals there but they are hard to come by.
My second gripe is they have become a MX/extreme sports version of My space. every day we were getting emails to go look at someones profile because they added new pictures of them walking down the street or whatever.
This last week my son went with a company that has done a great job of marketing several of the guys he races with and they get great deals and it is a true results based system where if you produce they up the level of support you get.
here is a link to his new profile which he just started putting together. If you look into this company i would appreciate you use his name as a reference as well
