In my opinion, a reverse rotation tiller is just trying to make up for poor tiller design in the first place... ALSO, there IS a learning curve to getting good tilth, just putting the tiller on and beating the soil to death (going too slow) is never a good choice...
I never plow before tilling, it's just not needed... a plough (if you prefer that spelling) really is a good was to make compaction, then you need a sub soiler ect... I prefer to do a proper job of tilling and nothing else is ever needed, also NOTHING incorporates green manure better than proper tilling and I add a LOT of green matter every year...
