Check out the putter selection guide form his website.  This will help in getting you started.

The larger the putter head (Futura X, GoLo, etc.) the better they are for a straight back straight through putting stroke. 
Smaller blade putters promote an arched approach.

Good luck! 

I have to agree with you on this Nathan..  At a golf shop a few weeks ago and was trying out the GoLo and you're correct about the straight back, straight through concept..  Felt really nice..  I have a Newport and at times i do feel the arch approach...

I'm looking at the GoLo putters as we speak but a used one :)

I think it's got more to do with the neck and toe flow (toe hang) than the size of the putter head.  If you like a Newport and want to putt SBST, try to find a long neck.  The less toe hang, the better if you're a SBST kind of player.

You can see the Longneck's toe hangs to about 8

A standard Newport hangs to about 7

It all depends on your putting style, etc.. Usually, the less toe flow, the better for "straight back" straight through. 

Scotty Cameron talks about his newest putter, X5, being a straight back straight thru putter.

The closer the shaft of the putter aligns to the center of the putter face, the more it is made for a straight stroke. The reverse is also true. If the shaft points to the far end of the face, the bigger the arch. What you will be looking for is a putter with no toe hang.

The neck type is more for offset. Plumber neck tends to have a large off set compared to some others that have the shaft go straight in the head. This helps with the angle of attack when matched with you preferred loft and shaft lean.

Head shape affects forgiveness and MOI. Larger heads have the COG further back and will be more forging on off center hits. Its the same physics as a driver. Large mallet heads also have a lot more area to draw and alignment line, and for some, that is the real game changer.

Chris,

If you look at the selection guide link Andrew posted, all the putters listed as "toe flow" minimal or nearly minimal should support the SBST putting stroke.

Find a head that you like, then find a center shaft.
