2016 Ripcurl flashbomb 5.5mm vs new flasbomb 5mm

[Soulmancer]

I was looking at a 2016 ripcurl flashbomb 5.5mm that I can get for 20% off... looks like it was discontinued and the new 5mm has more E5 lining coverage that now includes the chest and the arms... Any idea how this would compare for warmth, flexibility and weight?

I owned an older flashbomb 5mm from like 2013; it lasted me a few years and I was pretty happy with the suit... replaced it with an xcel 5mm revolt and I am less than happy with it, doesn't fit me as well, suit floods and it doesn't keep me nearly as warm as my old flashbomb did.
