I read the thread a while ago while I was toying with the lattice idea, though I must concur with you that there is not much draw, gamble really helps in this slot, though it is card disadvantages it usually fetch the card i need. The idea of the deck is not simply to set the lattice-rod lock as fast as possible than to control the mana sources in general. Anyway, I wanted to stay mono-R for color consistency and blood moon issues.  I've tried versions of the U/R and I feel much confortable than with the mono-R deck, since it seems that with U you are racing to lock down your opponent.  mycosynth golem, is a 4/5 affinity that gives affinity to your creatures thus helping to develop your beatdown under the lock if necessary.

I usually mulligan to have a 1st turn welder, except some brokeness happens. And except I get flooded with mana sources, I usually have enough answers or threats for the opponent to worry about.

Thanks for your comments,

I've been recently (these lasts months) toying with a mono-R control deck. It was created for a heavy control enviroment, though I've seen it has really fair matchups against the rest of the field. I would like to share this deck list with all of you and ask for constructive critizism.

How it works? Well, you have the classical welder tricks, and quite a good amount of acceleration. Depending on your play style and your opening hand you can go the lattice-rod, lattice-shamman way or try to go, beatdown-control mode. This deck is designed as control with a hard lock built in.
