What wrong with trading FD/May with a small amount of shares if it's more volatile than what you're used to?
Nothing wrong with trading less shares in volatile spreads, I do that, but FD/MAY is not my cup of tea. Just by looking at the 5 mins chart over the last month I know instantly this is not what i want to trade. It doesn't "regress to the mean" very often. That's why I stopped trading FRE/FNM last september. Too volatile as well, but also less mean reversion.
Some of my best performing pairs correlate less than 0,8 on a daily basis. There's a lot of good pairs hardly anyone trades. Spend time looking at volatility in sectors instead of just correlation. Very high correlation is no guarantee for mean reversion (my best pairs are around 0,8).
