Proper Re-buy strategy question

[TheNextLevel]

So I was reading some post about rebuy tournaments, and it seems like most people advocate re-buying at least 3 times and many upwards to 6 times a tournament. I know 2+2ers advocate making an immediate rebuy at the start of the tournament, but for myself I usually just make the initial rebuy and then ad-on after the break. I usually just try to double up on some donk LAG in the beginning (I play low stakes rebuy tournaments), and I usually finish out the break with above avg chips, but I'm usually never near the CL. I was just wondering is it bad to use only 2-3 rebuys (maybe 2 rebuys, and an ad-on) or should I just be playing really LAG in the beginning trying to accumulate a lot of chips and spend like 5+ rebuys trying to big a gigantic stack. Just curious to your thoughts. Thanks.
