I use Ilford MGIV RC Pearl finish paper, I have no problems whatsoever, getting snap in my prints.
You mentioned that your prints came in a little dark, is that dark as in flat prints looking a bit grey, or dark as in they are printed a bit dark?
Can you view your negs on a light box, are they flat, normal or contrasty?
Basically, your printing is a reflection of what you have in the negative.
It is possible you may need to change the film developing time, to get a contrast that suits your enlarger and enlarger lens combination
If you look at the film developers instructions you should find shorter time for condensor enlargers, longer time for diffused enlargers, is pretty much what is suggested.
Also what grade are you printing at? Are you using filters or no filters?
I realise you have been away from printing for a while, it will take a litle time to get back into the swing of things.
I would perservere with the MGIV RC Pearl combination, there is nothing wrong with it. It is also about the cheapest and quickest way, to tune yourself back into the darkroom.
What film have you used, by the way?
Answers to some, or all of these questions, should help us to get a handle on what may or may not be causing your flat prints.
