Hughes retro roller lifters and 10w30

I have the solid roller version, morel makes them for people "hyd/solid"...like Hughes, maybe even exclusively now since I bought mine through Doug Herbert for less money "$280.00" ..that was 2011.
I run 20 50w with them.... No where does morel say what oil weight to run, Hughes, once again... is full of it.
I bet there is an un measurable difference in cold oil flow between the 2...one that makes about zero diff in lifter life, but some are dreamers and it helps them sleep at night.. regardless im sure thats their angle with that advice.
Only 2 things with the lifters is to stay at or under 220seat/425 ish open... and keep the solid lash @ .014-.016. The 170lbs seat Hughes says is really odd and Imo overly cautious imo. What decent solid roller could you run and control, may as well stay solid.jmo
