Mate - anything you choose to go with should suit your budget, and profile for what you want out of it. I used to go with The Kennel (not even sure if that is a thing anymore) - then I just went with the yearly GA one - because I was not attending games. I've got a 15 month old now and a nephew who is dead keen on attending games - so in future years, I may bulk again and go with a higher package so we can enjoy the experience more.
If you think you'll attend x amount of games, then go ahead with a package that suits. If you like the benefits of the packages at the pointier end, then go with that. Don't feel like what you're doing needs to be put to a litmus test about what other people are doing - in my eyes - if you're a member for 1 game or 12, then you're member.
Membership is the lifeblood of any NRL club, so anything you can give to support them is always welcomed.
