Am I misplaying suited connectors???

[RiverDancer]

I'm concerned that suited connectors are hurting my winrate. I'm doing pretty well, generally averaging between 3-6 BB/100 month by month in 1/2 - 3/6 NL Holdem. After going through my database it seems like generally my biggest losing hands (BB/100 wise) are always suited connectors. I lose big with hands like 89s, JTs, 56s, etc when I feel like they should be winning hands in NLH. I have a typical tight/agressive profile 19/10/24, so I don't think I'm playing these hands more than most people would, but clearly I'm doing something wrong. If anyone who has better success than I with these kinds of hands has some advice I'd be very greatful.
