I too, am a ram prime fan. I've tried priming on the press (stock priming arm), handheld primers, and ram primers. I get excellent feel, and my thumbs don't get cramps. I have a C-H "C" style press with a ram prime tool permanently installed and just pull out the seating stem and swap it for different size primers. I haven't tried the RCBS style bench mounted priming tool, mainly 'cause I've found what's easy and works well for me.
Mebbe you could try champhering the primer pocket to allow a straight start for the primers...
