Raising weak players 3/6, 5/10 full

[winky51]

I have upped my raising quite a bit in the last 6 months. Where I used to be 5-6% PFS I am now 8-10%.

My logic is that is a weak player limps and he is the only one in the pot then I consider him not there for a hand I hold that I would normally raise 1st in. Im talking about non-premium. I assume he has a worse hand than mine in 95% of the cases and I have position.

Like a weak player limps UTG, I raise with 88 MP1. This is something I normally do.

A weak player limps EP2, I raise on the button with KJo.

A weak player limps MP1, I raise on the bitton A7s.

I am finding that my agression is changing my opponents. I get bluffed less at and they try for check raises more on the river.

Is this a reasonable line of play? I find it actually more fun and profitable.
