It kinda sounds like you already have decided against a Hyd. roller by stating the negative aspects. Are these things you have experienced previously, or are these what your builder has told you?
There are plenty of folks on this board who are running these type cams without experiencing failures, so maybe the technology has been improved. If you truly want to run one, then do yourself a favor and at least discuss it with some notable builders mentioned earlier.
I'm like ST. I'm running one in my FE with nary an issue.
