To buy a season ticket or not - My dilemma

Basically, im torn between whether to buy a season card or not. I've never been able to get one because of work and money, but im in my last year of cheap prices (being 21) so im trying to work out if it would be cheaper for me to buy one, even if I dont make all the games.
1) I work saturdays, and get a few off through holidays. Some of our games SHOULD be moved to sundays / mondays?!
2) my season ticket would be £335
3) What will ticket prices be like? Theres no discounts with the citycard this year (e.g. £5 off first 10 games), i'd estimate a ticket for a 21 year old will be £35? and more for derbies, top 4 games etc. (Last year derby tickets for me and my dad came to something like £90)
4) Limited availability left. All the good stands are sold out
5) they seem to be front rows; which means 1) RAIN and more importantly 2) I like to stand up!!
Many thanks for reading this! Im torn, and trying to work this out. Theres one or two mates thinking about this two. Another problem is that my dad won't be able to go through on my 21 card (?) which means the cost of him upgrading it if i dont go.
thanks for reading,
