logic flawed? NL limp or raise

[108suited]

1. Assumption - Ac Jd can't stand a raise, but 7s8s can stand a raise preflop.

2. Example - a. It's folded to me in a no limit game and I am on the button with As Jc. I decide to raise.

b. Same situation but I am on the button with 7s6s. This time I call.

3. Thoughts - If I just call with Ace Jack and it's raised, I will have to fold based on the assumption above. The 7s6s can stand a raise in position, again based on the assumption.

Is there any merit to raising more with a hand that can't stand a raise but calling more with a drawing type suited connector hand that can stand a raise?

Another problem with the small suited connectors is that normally if you miss the flop, you are not going to win in a showdown with hard card strength. If the AJ hand gets checked down your ace high may win the pot for you. The seven six hand will most likely need some help.
