Kant Twist - which sizes?

[ToolRoom]

I appreciate this might be an open ended question, but for the guys using Kant Twist clamps, which sizes do you find you use the most?

They are normally prohibitively expensive over here, but currently on sale so I want to pick up a few of the most common sizes for general workshop use, welding and perhaps on the mill.

I'm planning to go for a pair each of:

407 - 2 1/2" Deep
415 - 4 1/2" Deep

I'm also debating adding the small 1" model 401, but not sure how useful this size actually would be.
Any feedback welcomed to help me make a decision.

I have pretty much all of them, from 3/4" and up. I find I use the 2" through 4-1/2" the most. The 3/4" and 1" are of limited usefulness for most people. I rarely use the really big ones, either, reaching for a Bessey F-type clamp first.

Thanks MushCreek,

I figured that would probably be the case - I've a lot of big C and F clamps, and a selection of small toolmakers parallel clamps, so a fair bit of overlap. 4 inch seems to be the size I use for a lot of things. So the 415 seems a nice choice.

I may drop the 1" or swap them for some bigger ones, even for clamping small stuff on the mill 1" seems quite a small clamping range.

^^This pretty much mirrors my experience as well. Although on occasion I do use the larger Kant Twist when performing and awkward setup on the milling machine or fabrication table.
