First let me explain my chip collection
I have increments of:
25 (500 Chips)
100 (500 Chips)
500 (200 Chips)
1000 (100 Chips)
All are printed with custome stickers, the set looks pretty sweet, so I can not have any other increments, I will not get any other increments either, that is what I have to work with.
Here is the blind system I worked out, I figure it usually works great with 3000 or 3500 in chips.
25 - 50
50 - 100
75 - 150
100 - 200
150 - 300
200 - 400
300 - 600
400 - 800
500 - 1000(it never really gets higher than this)
700 - 1400
900 - 1800
1000 - 2000

The blind system seemed to be working fine, however I recently discovered two things that I don't like.
A) I read online that if you are lower than 30x the BB than you are on a short stack, well if you keep your 3000 in chips too the second blind stage, you are at 30x the BB.
B) I don't know if it is just because my friends suck at poker, but it always seems like the heads up match is around the 300-600 stage, and both players have huge chip stacks compared to that stage.( doesn't bother me, I usually make it that far)

Are these things I shouldn't worry about? Should I not try to fix something that I don't really think is broken? Would you play this blind system if you came to my house?

Thoughts? New ideas?
