I would think the max irons and 3 wood...with the Max balls....both are sold almost exclusively based on the slow meter. I'm not certain if they have a max driver..probably they do...but the Taylor Made M1s have a 4.5 out of 5 meter speed...thats pretty damn slow.
At any rate, you can go to the pro shop and check out which clubs and balls have the most dots or higher numbers for meter speed...they will be your slowest.
