I also know what happens when you loose a roller lifter, despite what people say...they can and will come apart.
. They are simple, and dont fly apart on you. With the cam specs I am looking at with this solid flat cam, the spring pressures would be pretty high with the same size roller.
I had a long discussion with Dwayne about a solid vs. roller on the street. I had talked myself out of a roller and was gonna get another flat tappet. Fine, you dont have to deal with checking the lifters on a regular basis, with a roller. As you mentioned, you will need some serious spring pressure with that flat tappet. A bunch of spring pressure on a cast core, over time (who knows how long) might equal breaking the core. 
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.
Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

Well I have to give those C***y guys a fair fight  and there I go thinking I was giving them two chances by keeping it heavy and N/A!
When this motor gets fixed they're all just gonna have to jet up their nitrous kits
